ABSTRACT:
A system and method for voltage controlled oscillator (VCO) biasing in low voltage circuits including low resistance elements that are especially susceptible to noise. In one embodiment, a poly resistor and triode resistor is used to cancel or offset the effects that temperature variations have on the circuit. The triode resistor is powered by a voltage source that uses a pair of diodes coupled to a constant transconductance (gm) circuit to generate a reduced noise voltage that is independent of the power supply noise. The size of the triode resistor and poly resistors can be varied.
