High Swing Bias Design for a Cascode Transistor

[Could not find the bibliography file(s) High Swing Bias A high swing bias scheme for a cascode transistor is shown in Figure 1. Assumptions Transistors M1-M5 are in saturation and Mx1-Mxn are in triode region Square law model of MOST is considered for analysis Consider the general case where M3 […]

Biasing Scheme for CMOS Telescopic Amplifier

Telescopic amplifier has higher DC gain due increased output resistance because of cascode transistor. The gain improvement is obtained at the cost of lower output swing. The output swing limitation comes from more number of devices in the stack and also due to biasing scheme employed for cascode transistors. Some […]

Distortion in RF Circuits

For a memoryless two port active network the input-output characteristic is generally a nonlinear function, that can be approximated by a polynomial over some signal range as (1)   If the input contains only one frequency component, the output contains desired fundamental frequency component and harmonics of the fundamental frequency […]
