The tendency of design of integrated circuits (ICs) goes to through the power and area reduction way. The surface area of very-large scale integrated circuits is shrinking along with the shrinking of technological dimensions. Power reduction requires usage of low-power design methodologies. The design of Switched-Opamp (SwOp) circuit based on typical Operational Transconductance Amplifier (OTA), with high efficiency is presented. Reduction of power consumption, using digitally controlled switches, is provided. The suggested SwOp was fabricated in a 14nm FinFET technology and achieved a DC gain of 38.4dB, a maximum operating frequency of 11.5GHz and a power consumption of 114.48uW for worst corner (SS) when the load capacitor is 5pF. The power consumption of proposed architecture is reduced about two times. Structure proposed in the paper can be integrated in modern analog-to-digital conversion application, high-speed receivers, memory systems.
