Abstract
본 논문은 저전력으로 동작하면서 Rail-to-rail 입력 범위를 가지는 센스 앰플리파이어를 제안한다. 새롭게 제안한 센스 앰플리파이어는 그라운드 전위부터 전원전압 전위까지의 입력을 수용하며 저전력 기능을 구현하고 있다. 방전전류 경로의 존재로 인한 정적 전력소모를 최소화 하는 것이 본 설계의 주요 요소이다. 새롭게 제시된 PMOS 입력신호 수신부와 그것을 제어하는 피드백 회로를 통하여 전력소모를 감소시킨다. 제안된 구조는 평균 소비 전력부분에 있어서 일반적인 Rail-to Rail 센스앰플리파이어의 약 50% 이상의 효율향상을 실험결과를 통해 보여준다
The newly designed sense amplifier in this paper has rail-to-rail input range achieving low power consumption. Reducing static power consumption generated due to DC path to ground is key element for low power consumption in this paper. The proposed sense amplifier performs power-saving operation using negative feedback circuit that controls the current flow with the newly added PMOS input terminal. As a simulation result, the proposed sense amplifier consumed about over 50 % efficiency of the average power consumed by the typical Rail-to-Rail sense amplifier.
