Dac for offset compensation
WebOct 17, 2024 · In this study, we describe a dual-chopper glitch-reduction current-feedback instrumentation amplifier (CFIA) with a ripple reduction loop. The amplifier employs the chopping technique to reduce low-frequency noise, such as 1/f noise. A glitch caused by chopping occurs at each chopper clock edge and results in intermodulation distortion … WebIn this work, a digital-to-analog converter (DAC) is presented, operated at the sensor array border and used for the compensation of the bias current deviations. The required data …
