Full wave rectifier having an operational amplifier |
摘要 |
A full wave rectifier comprises an input terminal supplied with an AC signal and an output terminal for delivering a rectified DC signal. An operational amplifier having an inverting input terminal, amplifies the AC signal. A rectifier gain setting is provided by a first resistor connected between the input terminal and the inverting terminal of the amplifier. A second resistor, having the same resistance as the first resistor, is connected between the inverting terminal and output terminal of the amplifier. A depletion type MOS FET operates responsive to the output of the amplifier, for performing a switching operation.
