| Abstract: | A novel charge amplifier is designed and its circuit is described.The circuit mainly consists of a current-current converter,an integral circuit,an analog switch circuit,and a steady current source circuit.The general purpose integrated circuits,the operational amplifier,and the analog switch are adopted to construct the charge amplifier circuit.The circuit is characterized by its high speed of conversion,wide range of input(about 400 pC) and simple circuit configuration.The introduced method and circuit shows a simple and low-cost way to design and develop multi-channel charge amplifiers.The charge amplifier circuit can be widely used in sensing devices. |
