Abstract

A reconfigurable current mode programmable multiphase sinusoidal oscillator is realized using digitally controlled low voltage CMOS current conveyors. The realized current mode programmable multiphase sinusoidal oscillator can provide independent digital control to its oscillating frequency through n-bit control words with high resolution capability, as well as reconfigurability. The realized multiphase oscillator is suitable as programmable analog module for current mode field programmable analog array. The programmable multiphase sinusoidal oscillator is designed and verified using PSPICE and the results thus obtained justify the theory.
