Parasitic-capacitance-insensitive voltage-mode MOSFET-C filters using differential current voltage conveyor

A new CMOS realization of the differential current voltage conveyor (DCVC) is introduced. The properties of the DCVC are shown to be suitable for very large-scale integration applications employing metal oxide semiconductor transistors operating in an ohmic region. A novel voltage-mode integrator is introduced. Detailed analysis of the parasitic capacitances is included. Voltage-mode continuous-time filters that benefit from the current processing capabilities at the input terminals of the DCVC are presented. Self-compensation of the proposed circuits is also presented. The effectiveness of the proposed circuits is demonstrated through HSPICE simulations based on the AMI 1.2μm N-well level 3 parameters.[PUBLICATION ABSTRACT]
