Drive Amp with Sample and Hold circuit
In this architecture, we propose the Drive amp with sample and hold circuit for offset compensation. In conventional architecture used only sample and hold circuit, we implemented the offset compensation mode in the Drive amp with sample and hold ciruit.
Whole sampling clock of TX lines are 113MHz and TX IN is conn..
Instrumentation Amplifier for Bio-magnetic signal Acquisition System
A biomedical signal processing system usually consists of a sensor, an IA with high CMRR, a low-pass filter, a sample and hold (S/H), and an analog-to-digital convertor (ADC). We designed an IA based on a current balancing technique with two differential pairs . A high-pass filter and a DC offset cancellation circui..
