Voltage sensing circuit

Abstract

A voltage sensing circuit consists of a sensing node, a transistor of a first conductivity type, a diode-like device, a first reference voltage source, a transistor of a second conductivity type, and a second reference voltage source. The transistor of a first conductivity type is configured with one source/drain receiving an input voltage signal and another source/drain connected to the sensing node. The diode-like device receives the input voltage signal and, accordingly, generates a voltage-dropped signal. The first reference voltage source is connected to a gate of the transistor of the first conductivity type. The transistor of a second conductivity type is configured with one source/drain connected to the sensing node and a gate receiving the voltage-dropped signal. The second reference voltage source is connected to another source/drain of the transistor of the second conductivity type.
