Abstract

A hot carrier measuring circuit of the present invention, which measures the characteristic degradation of a semiconductor device due to AC operation, includes a pulse generator generating at least two pulse signals which are partially overlapped with each other and have various duty ratios, a level shifter shifting the pulse signal which are generated in the pulse generator to a desired voltage level, and a measuring device receiving the pulse signals outputted from the level shifter to at least one terminal thereof.
