ABSTRACT:
The disclosed electrometer is of the type including an integrating amplifier and an electronically controlled switch. When the switch is closed, the electrometer is reset or cleared, and when the switch is open, the amplifier operates as an integrator. The switch is configured to substantially eliminate leakage currents between the switch and the inputs of the amplifier. The electrometer is operative for very small input currents and is operative over a wide dynamic range. The disclosed electrometer may be used to implement a highly accurate pressure transducer.
