Differential charge pump with low voltage common mode feedback circuit |
摘要 |
A differential charge pump utilizing a common mode feedback circuit. The charge pump includes a dual reference current source and outputs a differential current signal by modifying currents routed to the outputs utilizing current paths having transistors maintained in the linear region within the current paths. The common mode feedback circuit includes differential transistors requiring a maximum power supply voltage of a common mode reference voltage plus a transistor threshold voltage.
