Band pass filter with a switched capacitor |
摘要 |
A switched capacitor circuit has: first and second power sources; an operational amplifier driven by the power sources; a feedback capacitor connected to the inverting input terminal and the output terminal of the amplifier; a switched capacitor connected between a signal input terminal which receives an input signal voltage and the inverting input terminal of the amplifier; switching circuits for controlling the charging and discharging operations of the switched capacitor; and a bias circuit which is connected between the power sources and which applies a predetermined voltage to the non-inverting input terminal of the amplifier.
