概要

論文の詳細を見る
This paper describes the operation and the test results of a novel comparator, called a differential voltage (ΔV) comparator, which detects the difference between two input signal voltages. This comparator utilizes variable threshold voltage inverters (VT-INVs) which can change a logic threshold continuously using a variable channel size MOSFETs (VS-MOSs). The circuit configuration is very simple, and has the potential to achieve high integration and low power consumption in mixed signal system LSIs.
