A rectifier circuit includes three operational amplifiers (8, 9, 17), the first (8) of which is provided with feedback loops containing diodes (7, 18) of opposite polarity. The other op- amps (9, 17) are coupled to the output of the first one via the respective diodes, and to the circuit input via respective resistors 4, 15 having a value of twice that of the other resistors, so as to provide a positive going full wave rectified output at terminal 20, and a similar negative going output at terminal 12. <IMAGE> |
