Self biased low noise high PSRR constant GM for VCO

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