Chopper Stabilized Low Resistance Comparator
The paper describes an improvement of the chopper method for elimination of parasitic voltages in a low resistance comparison and measurement procedure. The basic circuit diagram along with a short description of the working principle are presented and the appropriate low resistance comparator prototype was designed and realized. Preliminary examinations confirm the possibility of measuring ext...
متن کاملAn Automatic Dc Current Comparator Resistance Bridge
The principle of the Direct Current Comparator has been around for some 30 years, however, very little work has been done towards automation. This paper describes a bridge for measuring resistance ratios in the range of 0.001 ohms to 10,000 ohms using a microprocessor controlled automated DC Current Comparator with IEEE-488 to an uncertainty of better than 0.1 ppm from 1 ohm to 1000 ohms and 0....
متن کاملA high speed low input current low voltage CMOS current comparator
A new high speed low input current comparator is proposed in this paper. Based on a simple negative feedback scheme around the transimpedance stage with an emphasis on a very large loop-gain, the transformed voltage signal is maintained at the lowest swing that results in a speed improvement. On a 0.25um TSMC CMOS process, simulation results demonstrate propagation delays of 3.6ns with ±100nA i...
متن کاملLow Power Low Noise CMOS Chopper Amplifier
AbstractChopping is a proficient way to reduce the low frequency offset and 1/f noise in amplifiers. In this paper, a low power low noise CMOS chopper amplifier is presented. It is composed of a two stage amplifier. The first stage’s high output impedance and the equivalent Miller capacitance of the second stage constitute together a low pass filter, which reduces the power consumption. The cir...
متن کاملIsolated ramping current sources for a cryogenic current comparator bridge
The design and perfonnance of a pair of highly isolated ramping and reversing direct-current sources for use with a cryogenic current comparator resistance bridge and dc superconducting quantum interference device (SQUID) detector are described. The current sources are floating and isolated from one another, and are internally programmed to reverse the output current while maintaining the SQUID...
