Modified Sigma-Delta Converter and Flip-Flop Circuits Used for Capacitance Measuring
Original language description
The paper brings new information about small capacitance measuring system based on modified sigma-delta converter (MSDC) with compensated loop based on phase locked loop (PLL). The system use of the 2 current sources and can be modified for other electrical or non-electrical quantity which will break the value symmetry in circuit, e.g. light intensity can be also measured with photodiode connected parallel to current source. Measuring system can work in open loop (direct sigma-delta converter) or closedloop (PLL). The system has the voltage and digital output and in closed loop can be supposed as a voltage controlled oscillator which is locked to input clock frequency. The simple flip-flop sensor for capacitance, or some other measuring is also described. In this paper, theoretical principle of the system, simulation and experimental results are shown.
