DVCC Based Current Mode and Voltage Mode PID Controller

Mohd.Shahbaz Alam

The demand of electronic circuit with extremely low supply voltages and power consumption is important in development of microelectronic technologies. So, in this paper a Voltage mode and current mode DVCC based Proportional Integral Derivative Controller Configuration is proposed. The circuits use two DVCCs as active elements and together with two capacitors and three resistors as passive elements. The new configurations offer very high input impedance, which enables easy cascading and enjoy good performances. The theoretical results are verified with PSPICE simulations using a CMOS realization of DVCC.
