Low Noise Amplifier for 1-10GHz Application

The design revolves around precise calculations related to input impedance, output impedance, and the gain of the circuit. In addition, TSMC 0. The LNA is biased with two different voltage supplies in order to reduce power consumption.

They can be categorized into two divergent classes according to the frequency at which they operate. The system working from 3. The main architecture of both UWB receiver and transmitter is demonstrated in Figure 1.

The BPF selects the signal between two desired frequencies. Besides, it should amplify the signal properly during the desired frequencies. In addition, VGA is supposed to control its own gain appropriately so as to create a proper signal level for analog-to-digital converter ADC. Many works have been proposed to achieve appropriate objectives required in the system. In other words, criteria such as lower power consumption, flat gain, noise figure during the bandwidth, stability, and linearity have been widely scrutinized.

Different techniques consisting of Chebyshev filter amplifiers, feedback amplifiers, and distributed amplifiers have been used [ 1 — 10 ].

Indeed, the minimum power consumption was obtained by utilizing Chebyshev filter [ 7 ]. The best power gain, however, was obtained by feedback amplifiers [ 8 ]. In addition, distributed amplifiers had the best input impedance matching among all works [ 8 ]. Ultimately, feedback amplifiers had the best noise figure [ 10 ].

Owing to the fact that the life expectancy of an LNA is predicated upon its power consumption, the power consumption should be considerably minimized. Successful approaches such as current-reuse topology and forward body bias technique are utilized to bring down the power consumption [ 11 — 15 ]. Besides, the equivalent circuit of the cascode LNA is depicted in Figure 3. Each part is analyzed separately so as to be scrutinized more precisely.

A band pass filter or Chebyshev filter is utilized to assist the LNA to amplify the signal across the desired frequency, demonstrated in Figure 4. The inductors and capacitors in the filter are calculated by. The most famous formula used to calculate the input impedance of the circuit is given by [ 16 — 18 ]. It is proved that the formula has a drastic error in both imaginary and real parts [ 19 , 20 ].

Owing to the fact that Lg, Ls, and Ld are designed by the formulas of Zin, Zout, and gain, the error stemming from the formulas brings about an extreme error in calculating the aforementioned elements. Hence, new and precise calculation is required to bring down the error stemming from equation 2.

The common-source LNA and its equivalent circuit are demonstrated in Figures 5 and 6. The calculated values for Chebyshev filter is used in both input and output of the circuit. In other words, the filter designed for the input of the circuit is the same as the filter used in the output of the circuit. After solving the circuit shown in Figure 6 , the gain, the input impedance, and the output impedance of the common-source LNA are given by equations 3 — 5. In order to demonstrate the considerable error coming from miscalculation of input impedance, output impedance, or gain, the input impedance is simulated by HSPICE and compared to the formula which has been utilized to calculate Lg, Ls, and Ld, depicted in Figure 7.

As can be observed in Figure 7 , both imaginary and real parts of the Zin are demonstrated. Hence, the real part of Zin should be 50 and the imaginary part should be 0. The elements are designed by the precise formulas and the output is demonstrated in Figure 7. It can be obviously observed that the error between imaginary parts and real parts of the precise formulas, calculated in this paper, and HSPICE simulation is zero. The aforementioned comments are applicable to both gain and output impedance.

Hence, barely can elements be accurately designed by the formulas which have been proposed so far. Indeed, the more precise the formulas are, the more accurate the design will be. The LNA and its equivalent circuit are depicted in Figures 8 and 9. Furthermore, it is utilized to enhance s21 too.

Consequently, the main purpose of the cascode LNA is to amplify the signal appropriately. Hence, the calculation of the gain is calculated by solving the circuit existing in Figure 9. The gain of the cascode LNA is given by. The calculated formulas might be considered long and complicated. One of the main objectives of the proposed LNA is having the minimum power consumption. Therefore, biasing technique and voltage supply are crucially significant.

This technique reduces power consumption in the common-source LNA, thus decreasing the power consumption in the whole circuit. Besides, each of the transistors is biased in different regions. The simulated results are depicted in Figures 10 — The stability of the circuit has been evaluated by. The noise figure is shown in Figure 11 and it varies from 2.

The noise performance of the LNA is better at higher frequencies. The linearity of the LNA is simulated at 7. All results and the FOM are compared to other works in Table 1. The FOM is enhanced appreciably because of the power consumption and appropriate noise figure. Furthermore, the maximum rate of noise figure is used to calculate the FOM.

As always, trade-offs can be mentioned in all parameters. For instance, if VDD1 is increased to 0. In fact, the trade-off is between power consumption and power gain and noise figure. Indeed, by increasing VDD1 to 0. In addition, even in comparison to other works, the power consumption is acceptable. An ultra-wideband ultralow power LNA is proposed in this paper. The calculation and power consumption are the principal objectives of this paper.

The sizes of transistors have been scaled down to nanometre, and the calculations proposed in this paper are applicable to all sizes of CMOS transistors. Since the purpose is the calculation and design, the implementation is not carried out. Nevertheless, many works have proved that the simulation results and the measured results are practically close to each other.

Made from the late 's into the early 's, these were various returns from the field and were, for various reasons, declared dead or not economically unrepairable. Since it will often cost about as much to repair a unit as to replace it, "dead" units are often put in bone yard and used as a source for mechanical parts to repair other units.

This amplifier is a part of a large rack of equipment running on the traditional 24VDC, positive ground telecom power system bus. In its original form, the amplifier is very robust and heavy, since it is rated for continuous duty, Class A operation.


Ku Uplink hardware operates in the range This has been achieved by the inclusion of Inductive and Capacitive elements within the FET structure. Semiconductor manufacturers deliberately include these "Reactive" elements to provide "stable" Gain across the nominal Pass Band and NOT beyond. The result is that these additional Reactive components have a minimal effect within the Pass Band of the device but these same components cause the device Gain to degrade outside of this nominal Pass Band. However, there is one caveat on this Modification process!
