V–I converter-based voltage-controlled oscillator with improved linear gain characteristic

A voltage–current (V–I) converter-based voltage-controlled oscillator (VCO) is adapted to generate multiple-phase clocks for clock and data recovery for a display driver IC. The proposed V–I converter changed the second-order current equation of the VCO to a first-order current equation of the VCO,...
