Abstract
A charge sensitive amplifier circuit for sensor frontend comprises an input node to be connected to a sensor to receive an input charge, and an output node to be connected to a charge conversion circuit. The charge sensitive amplifier circuit comprises a first transfer switch located between the input node and the output node to transfer the input charge to the output node. The charge sensitive amplifier circuit further comprises a second transfer switch located in parallel to the first transfer switch between the input node and the output node to transfer the input charge to the output node.
