Transcapacitance amplifier installation

Two-dimensional materials 2DMs are a promising alternative to complement and upgrade high-frequency electronics. However, in order to boost their adoption, the availability of numerical tools and physically-based models able to support the experimental activities and to provide them with useful guidelines becomes essential. In this context, we propose a theoretical approach that combines numerical simulations and small-signal modeling to analyze 2DM-based FETs for radio-frequency applications. This multi-scale scheme takes into account non-idealities, such as interface traps, carrier velocity saturation, or short channel effects, by means of self-consistent physics-based numerical calculations that later feed the circuit level via a small-signal model based on the dynamic intrinsic capacitances of the device. At the circuit stage, the possibilities range from the evaluation of the performance of a single device to the design of complex circuits combining multiple transistors. In this work, we validate our scheme against experimental results and exemplify its use and capability assessing the impact of the channel scaling on the performance of MoS 2 -based FETs targeting RF applications.

Trans-capacitance amplifier with picoAmperes input biasing and large output swing

According to some embodiments, a trans-capacitance amplifier is exhibiting an input current of the biasing in the range of picoAmperes while allowing large output swings. The trans-capacitance amplifier comprises an operational amplifier, a feedback capacitor, circuitry to DC bias and to AC ground the non-inverting input of the operational amplifier, and circuitry to DC bias the inverting input of the operational amplifier. According to some embodiments, the circuitry to bias the inverting input comprises a cascade of degenerated differential pairs. The first transistor of the first pair and the second transistor of the last pair have an active load. The cascade of differential pairs and the active load create a trans-conductance amplifier with a very low equivalent trans-conductance.

Low-Noise and Low-Power Interface Circuits Design for Integrated CMOS-MEMS Inertial Sensors

In electronics , a transimpedance amplifier TIA is a current to voltage converter, almost exclusively implemented with one or more operational amplifiers. Current to voltage converters are used with sensors that have a current response that is more linear than the voltage response. The transimpedance amplifier presents a low impedance to the photodiode and isolates it from the output voltage of the operational amplifier. In its simplest form a transimpedance amplifier has just a large valued feedback resistor, R f. The gain of the amplifer is set by this resistor and because the amplifier is in an inverting configuration, has a value of -R f. There are several different configurations of transimpedance amplifiers, each suited to a particular application. The one factor they all have in common is the requirement to convert the low-level current of a sensor to a voltage.
