Latest Patents

One of her latest patents is an interface circuit that can switch between single-ended transmission and differential transmission. The objective of this invention is to reduce the area of an output stage driver in an interface circuit that switches between two transmission systems. The interface circuit features two driver circuits and a drive control circuit that can alternate between a voltage driving system and a current driving system. These driver circuits are connected to a power supply potential via the drive control circuit. Two input signals and their inverted logic signals are inputted through a selection circuit. Based on a control signal inputted into the drive control circuit, the interface circuit can switch between the voltage-driving type single-ended transmission system and the current driving type differential transmission system.

Another notable patent is a Phase-Locked Loop (PLL) circuit. This PLL comprises a current-controlled oscillator that generates an output clock signal based on a current signal derived from the phase difference between a reference clock signal and a feedback clock signal. It also includes a current source and an initialization switch that performs an open/close operation based on the initialization signal. The initialization switch is inserted in series to the input terminal of the current-controlled oscillator and the current source.
