| Abstract | An amplifier circuit for operation with a signal source of predetermined high impedance, has repeater operable at low voltage with two unipolar transistors having controlled current transfer ratio, the circuit including an amplifier (102), an input coupling circuit (101a) for coupling the source to the amplifier and providing a high-to-low impendance conversion between the source and the amplifier, and a like coupling circuit (101b) for providing to the amplifier substantially solely a signal equal to an unwanted signal provided to the amplifier by the input coupling circuit, whereby the amplifier output is substantially solely an amplified version of the signal from the source. |
