Linearity evaluation technique for CMOS differential amplifier Abstract: A very important block in VLSI CMOS analog design, the classical differential amplifier presents the disadvantage of the nonlinearity of the transfer characteristic, especially for large values of the differential input voltage amplitude, this undesired behavior being concretized in large distortions introduced by the circuit. The proposed approach of the CMOS differential amplifier solves in an intuitive manner the quantitative and quantitative evaluation of the circuit nonlinearity by using an expansion in Taylor series of the amplifier transfer function. Additionally, a very simple and efficient linearization technique will be proposed, based on the compensation of the quadratic characteristic of the MOS transistor biased in saturation by using complementary current-mode square-root circuits.

Differential Amplifier-Quantitative Analysis (In Hindi)
The output offset voltage is the voltage which appears at the output of the differential amplifier when the input terminals are connected together. Why Differential? Another advantage of diff amp. Basic Differential Pair l Amplify diff signal. High rejection of supply noise, high output swings, etc.
What if input CM level changes? Diff Pair cont. V higher than the value calculated in a? Therefore PMOS overdrive voltage must be sufficiently low. As a result CM signal range is reduced. Gain can be increased by factor of 5. Single-ended Differential Voltage Gain. Solution to low-gain problem: Cascoding.

A differential amplifier is a type of electronic amplifier that amplifies the difference between two input voltages but suppresses any voltage common to the two inputs. Single amplifiers are usually implemented by either adding the appropriate feedback resistors to a standard op-amp , or with a dedicated integrated circuit containing internal feedback resistors. It is also a common sub-component of larger integrated circuits handling analog signals. In practice, however, the gain is not quite equal for the two inputs.

Many synthetic gene circuits are restricted to single-use applications or require iterative refinement for incorporation into complex systems. One example is the recombinase-based digitizer circuit, which has been used to improve weak or leaky biological signals. Here we present a workflow to quantitatively define digitizer performance and predict responses to different input signals. Using a combination of signal-to-noise ratio SNR , area under a receiver operating characteristic curve AUC , and fold change FC , we evaluate three small-molecule inducible digitizer designs demonstrating FC up to x and SNR up to 3.

This unit is primary making the jump between analyzing transistors with the understanding they are voltage-controlled current sources to building core analog circuit from these devices leading to basic amplifier design. Lectures from Dr. This project will consider source follower and common source amplifier. This project will require the design of amplifier using a transconductance topology. In particular, you will use a 9-transistor amplifier design and add the appropriate cascode devices.
