Latest Patents

One of his latest patents is a driving circuit that eliminates the effects of ambient temperature variations and increases driving capacity. This invention includes two-stage CMOS inverters that invert and amplify the input signal. A rising edge detector identifies the rising edge of the input signal and outputs a detection signal with a pulse width corresponding to ambient temperature. A PMOS transistor drives the output node to the power supply potential based on this signal, while a falling edge detector performs a similar function for the falling edge of the input signal. This innovation effectively restrains delay time variation in driving circuits due to changes in ambient temperature.

Another significant patent involves a semiconductor integrated circuit that contains multiple processing circuits executing necessary processes alongside data holding circuits. A control signal generating circuit produces control signals based on a first clock signal, a second clock signal, and a mode setting signal. The operation of each scanpath circuit is controlled according to these generated signals, allowing for a reduced size of the semiconductor integrated circuit.
