Patent ID: 8305139

Claim:
A circuital arrangement adapted to provide a first output voltage to a first output terminal and a second output voltage to a second output terminal, comprising: a first transistor configured to receive a first control voltage; a second transistor configured to receive a second control voltage; a first capacitor connected with the first transistor on one end and the second transistor on another end; a third transistor configured to receive the second control voltage; a fourth transistor configured to receive the first control voltage; and a second capacitor connected with the third transistor on one end and the fourth transistor on another end, wherein: the first capacitor is configured to store charge when the first transistor is switched on and is configured to couple a first capacitor voltage to the first output terminal when the first transistor is switched off, wherein the first and second output voltages are functions of the first capacitor voltage when the first transistor is switched off, and the second capacitor is configured to store charge when the third transistor is switched on and is configured to couple a second capacitor voltage to the second output terminal when the third transistor is switched off, wherein the first and second output voltages are functions of the second capacitor voltage when the third transistor is switched off.
