Abstract

PURPOSE:To obtain a switched capacitor inductance having a small internal gain by providing capacitors, equipped with a rotary switch across each one, at the input and output sides of an operational amplifier. CONSTITUTION:Numbers of rotary switches provided to capacitors C10 correspond to those given to periods of a clock, and rotary switches are connected at times equivalent to the numbers of the clock. Capacitors C10 sample and transfer the charge of an input signal to integrating capacitor Ca and then sample and transfer the charge of the output signal of operational amplifier AMP to the input side. Namely, two capacitors C10 operate at an interval of one period time. Thus, the switched capacitor inductance can be obtained which has a small internal gain and the large dynamic range of the circuit.
