Bidirectional current conveyer with chopper stabilization and dynamic element matching
2012 IEEE International Symposium on Circuits and Systems, 2012A compact and accurate current conveyer for interfacing with a three-electrode electrochemical sensor is presented. It employs chopper stabilization to reduce transistor sizes for a given flicker noise. A current-copying circuit generates a mirror image of the sensor current for bidirectional conveying. It employs dynamic element matching to remove the

Chopper-stabilized instrumentation amplifier with reconfigurable inverting/non-inverting modes
2014 International Symposium on Next-Generation Electronics (ISNE), 2014A chopper-stabilized instrumentation amplifier (IA) with reconfigurable inverting and non-inverting modes is realized in CMOS 0.35um technology. A resistive feedback network is proposed to increase gain by lowering the resistance, which eliminates the conventional need for high resistance values.

Chopper stabilized CMOS integrated front-end for magnetic field measurement
IECON 2006 - 32nd Annual Conference on IEEE Industrial Electronics, 2006This paper presents an analogue front-end dedicated to magnetic field measurement that is intended to be used in a mixed signal submicron CMOS microsystem. The front-end features a Hall device and its biasing circuitry both associated to a nested chopper-like structure. This system efficiently removes 1/f noise and reduces offset. The biasing amplifier

Biosensors and Bioelectronics, 2012
A new method that can improve gas-chromatography-electroantennographic detection (GC-EAD) by orders of magnitude through a technique known as chopper stabilization combined with matched filtering in colored noise is presented. The EAD is a physiological recording from the antenna of an insect which can be used to find compounds in the GC effluent that ...

Stability of chopper‐controlled DC series motor under regenerative braking
Electrical Engineering in Japan, 1978An entire system of the chopper-controlled dc series motor is derived taking into account the core saturation, response delay of field flux, etc. First an equivalent linear model is derived and then its transfer function for a small disturbance is derived.

Stability Enhancement using a DC-Chopper, Crowbar, and FACTS Device
2020A fixed speed wind turbine generator system that uses induction generator as a wind generator has the stability problem similar to a synchronous generator. On the other hand, a doubly fed induction generator (DFIG) has the flexibility to control its real and reactive powers independently while being operated in variable speed mode. This chapter focuses
