Abstract
A voltage controlled oscillator circuit includes a predetermined number of interconnected differential comparator cells having source connected p-channel and n-channel transistors, a biasing transistor connected to the sources of the p-channel or n-channel transistors, and clamping circuits connected to said first and second n-channel transistors. The voltage controlled oscillator circuit further includes filter circuitry for filtering the input currents to the biasing transistor.
