Abstract
A sensing circuit is provided. The sensing circuit includes a sample and hold circuit and a gain amplifier. The sample and hold circuit includes a first charging path and a second charging path. The first charging path selectively generates a first charging potential between a first sensing terminal and a first reference terminal according to the analog voltage signal and a reference voltage. The second charging path selectively conducts the reference voltage to a second sensing terminal. A pair of differential input signals are generated at the first sensing terminal and the second sensing terminal. The first charging path and the second charging path are implemented by high voltage components. The gain amplifier receives the pair of differential input signals through a first and a second input terminals and generates a pair of differential output signals at a first and a second output terminals.
