Abstract :
A new CMOS realization of the differential current voltage conveyor (DCVC) is introduced. The properties of the DCVC are shown to be suitable for VLSI applications employing MOS transistors operating in the ohmic region. A novel electrically tuned MOS-C quadrature oscillator with orthogonal control over the frequency and condition of oscillation is introduced. Additional precise digital trimming can be achieved using the current division network. Compensation techniques for the finite frequency response are presented. Both the experimental results and HSpice simulations are in good agreement with the theoretical analysis
