ABSTRACT:
Low-power-dissipation CMOS oscillator circuits include inductors and capacitors forming tank circuitry. Cross-connected MOS devices provide positive feedback to replenish losses in the tank circuitry and thereby sustain oscillations. Each such oscillator circuit simultaneously generates complementary output sine-wave signals.
