Abstract:
1. A current conveyor circuit, comprising: a first low impedance input to receive a first input control signal; an output having a high impedance to supply an output current signal proportional to said first input control signal; a first transistor having an input to receive said first input control signal and having a first differential output to supply a first differential current signal to said first differential output; a second low impedance input to receive a second input control signal, said control signal having an opposite sign with respect to said first input control signal; a second transistor having an input to receive said second input control signal and having a second differential output to supply a second differential current signal to said second differential output, said second differential current signal having an opposite sign with respect to said first differential current signal; a third transistor having an input operatively coupled to said first transistor input and an output to supply a third differential current signal; a fourth transistor having an input operatively coupled to said first transistor input and an output to supply a fourth differential current signal; a fifth transistor having an input operatively coupled to said fourth transistor and an output to supply a first differential voltage signal; a sixth transistor having an input operative coupled to said fifth transistor input and an output to supply a second differential voltage signal; a seventh transistor having an input operatively coupled to said first transistor and an output to supply a third differential voltage signal; and an eighth transistor having an input operatively coupled to said input of said seventh transistor and an output to supply a fourth differential voltage signal.
