Abstract
The invention relates to the electrical measurement engineering and radio electronics and may be used for high-accuracy reproduction of floating admittances represented in the cartesian coordonates.The admittance converter comprises two contacts (2, 3), a differential amplifier (1), the noninverting and inverting inputs of which are connected to the contacts (2, 3), correspondingly, two programmable amplifiers (4, 5) with controllable transfer constants in the interval of positive and negative values, the inputs of which are connected to the output of the differential amplifier (1), a phase shifter (6) with a phase shift of 90°, the input of which is connected to the output of the programmable amplifier (4), two voltage-to-current converters (7, 8) with equal conversion factors, the outputs of which are connected to the contacts (2, 3), correspondingly. The voltage-to-current converters (7, 8) are provided with differential inputs. The output of the programmable amplifier (5) is connected to the noninverting input of the voltage-to-current converter (7) and to the inverting input of the voltage-to-current converter (8), and the output of the phase shifter (6) is connected to the inverting input of the voltage-to-current converter (7) and to the noninverting input of the voltage-to-current converter (8).
