Abstract
A voltage controlled oscillator (VCO) includes a voltage controlled load. The voltage controlled load supplies additional capacitive loading to the VCO, via a transmission gate, at low frequencies to decrease the frequency-gain factor of the VCO. Moreover, at high frequencies, the effect of the voltage controlled load is minimized by turning off the transmission gate thereby allowing the VCO to operate at maximum frequency for worst case speed conditions.
