Abstract: PURPOSE:To enable an accurate measurement at low cost by forming a closed loop with a DC adder circuit, sinewave eliminating circuit, voltage comparator and deviation amplifier, and superimposing a DC voltage on the sinewave by a feedback operation of this loop. CONSTITUTION:The sinewave outputted from a sinewave generating device 1 is added to the DC voltage outputted from a DC voltage generating device 13 by the DC adder circuit 3 and converted to a sinewave signal superimposed on the DC voltage, then impressed to an electrostatic capacitance 5 to be measured. This voltage is taken out to the sinewave eliminating circuit 11 to eliminate the sinewave, and the DC voltage supplied to the electrostatic capacitance to be measured is taken out. The voltage is compared with the DC voltage outputted from the device 13 by the voltage comparator 12 to obtain a deviation voltage and amplified by the deviation amplifier 14, then supplied to the input terminal of DC voltage in the DC adding circuit 3. By the feedback operation of this closed loop, the DC voltage is superimposed on the sinewave. That is, the device can be made at low cost since a floating type DC voltage generating device is not used, and the accurate measurement can be performed with restraining the generation of noise.

Title: Balanced conversion circuit
Inventor: SUGITA HAJIME
IPC: H03F3/45
Filed: 1987-12-21
Abstract: PURPOSE:To output a well-balanced balanced signal by connecting amplification circuits of the same circuit constitution to each input terminal of a differential amplifier, and impressing an unbalanced signal to both the amplification circuits at the same amplitude and the same phase. CONSTITUTION:An FET 13 and the FET 14 are connected deferentially, and the drain of the FET 5 and a resistor 7 are connected to the gate of the FET 13, and the drain of the FET 6 and the resistor 8 are connected to the gate of the FET 14, and it is assumed that the FET 5 and the FET 6 are the same FET and the resistor 7 and the resistor 8 are the same in their resistance values. When the DC voltage of an input terminal 1 changes, currents to flow in the FET 5 and the FET 6 change, and the drain voltage of the FET 5 and the drain voltage of the FET 6 change in the same way, but a potential difference is not generated. Thus, because an equilibrium condition is not ill balanced by the output impedance and the output DC voltage of a preceding circuit, and the DC potential difference of the balanced output terminals 3, 4 comes always to be zero, the well-balanced balanced signal can be outputted even in the case of multistage connection.
