ABSTRACT:
A circuit is disclosed that comprises a capacitor gain-boost circuit and an amplifier coupled to capacitor gain-boost circuit. A capacitor gain-boost circuit comprises of capacitor, gain-boost amplifier and biasing circuit. The gain-boost amplifier and capacitor provides optimum biasing operation and performance. Accordingly, through the use of capacitor gain-boost circuit, the supply voltage range and power consumption of an amplifier is optimized while the gain of amplifier is improved.
