CHARGE AMPLIFIER WITH MINIMUM OFFSET VOLTAGE Abstract of the Disclosure A charge amplifier having minimum offset voltage such as for use in processing a signal from a capacitive transducer. The amplifier is arranged to minimize the offset voltage and drift. The amplifier is arranged to be reset to zero upon application of supply voltage thereto, and the resetting circuit is arranged to reset the amplifier automatically during an adjustable interval after application of the supply voltage. The charge amplifier is further compensated for temperature variation and is arranged at minimum offset voltage notwithstanding strong background noise. The amplifier is arranged to have a drift of no more than a fraction of a millivolt per second. The amplifier circuit includes an improved switching arrangement and may utilize a second amplifier circuit for effecting temperature compensation.
