Abstract
The invention relates to electric measurement technique and radio electronics and can be used for high-accuracy reproduction of current-controlled impedances of any nature with the possibility of independent control of active and reactive components. The impedance converter comprises an operational amplifier (1), a first resistor (2), having one contact connected to the output of the operational amplifier (1) and the second contact to its inverting input and the first terminal (3), a second resistor (4), having one contact connected to the mass and the second terminal (5), and the second contact to the non-inverting input of the operational amplifier (1). The impedance converter further comprises the first differential amplifier (6), the first input of which is connected to the output of the operational amplifier (1), and the second input to its non-inverting input and the output of the second differential amplifier (12), the first input of which is connected to the output of a phase shifter (11) with a phase shift of 90?, the input of which is connected to the output of the first programmable amplifier (10), and the second input of the differential amplifier (12) to the output of the second programmable amplifier (9). The programmable amplifiers (9, 10) are made with transfer coefficients adjustable within -1...+1. The impedance converter additionally comprises the third (7) and fourth (8) programmable amplifiers with step-controlled transfer coefficients, the inputs of which are connected to the output of the first differential amplifier (6), and the outputs, respectively, to the input of the first (10) and second (9) programmable amplifiers.
