A CMOS chopper amplifier [PDF]
IEEE Journal of Solid-State Circuits, 1986 This paper presents a CMOS chopper amplifier realized with a 2nd order low-pass selective amplifier, using continuous-time filtering technique. The circuit has been integrated in a 3 ?m p-well low-voltage CMOS technology. The chopper DC gain is 32 dB with 200 Hz bandwidth.

International Journal of Trend in Scientific Research and Development, 2018 In this work, a highly linear Cascode CMOS LNA is presented. Linearity issues in RF receiver frontend are discussed, followed by an analysis of the specifications and requirements of a LNA through consideration of multi standard LNA. Device non linear characteristics cause linearity problems in the RF front end system.

Digital Detection of Oxide Breakdown and Life-Time Extension in Submicron CMOS Technology [PDF]
, 2008 An approach is introduced to extend the lifetime of high-voltage analog circuits in CMOS technologies based on redundancy, like that known for DRAMS. A large power transistor is segmented into N smaller ones in parallel. If a sub-transistor is broken, it
