  • Voltage regulator with switching and low dropout modes
    Patent number: 10320290
    Abstract: A voltage regulator includes an input terminal, an output terminal, a control circuitry, a buck mode switching converter, and a low dropout regulator circuit. The buck mode switching converter is arranged to convert a voltage signal received at the input terminal to a first voltage signal at the output terminal responsive to a first predetermined signal output from the control circuitry. The buck mode switching converter includes an electronically controlled switch in communication with an energy storage element. The low dropout regulator circuit is coupled between the input terminal and the output terminal and includes a linear circuit and is arranged to control a voltage drop across the linear circuit so as to provide a second voltage signal at the output terminal responsive to a second predetermined signal output from the control circuitry.
    Type: Grant

  • Low power wide swing current mirror
    Patent number: 6617915
    Abstract: A low power wide swing current mirror circuit wherein the signal current is separated from the bias current, and a bias current sink is connected in parallel with a current mirror so as to shunt the bias current to the circuit common.
