The charge pump output voltage temperature compensation circuit is characterized in that a temperature compensation diode is connected between an output end of the charge pump and the divider resistor. According to the charge pump output voltage temperature compensation circuit, a negative temperature ...
架构一：串联电压倍增器（cascaded voltage doublers）其中，transfer capacitors Ci与Ci'均设为C，而两对cross-coupled self-boosted pass transistors（Ni与Ni'，以及Pi与Pi'）则由nonoverlapping phase进行控制。该架构的工作状态可简要描述如下：phase1：在φ1=Vdd且φ2=0的条件下，N1和P1'保持导通，而N1'和P1...
The present invention relates to a charge pump capable of enhancing power efficiency and output voltage, which comprises a pump capacitor, a switching module, a first switch, a first buffer, a first switch, and an output capacitor. The switching module is coupled to a first terminal of the ...
Since I don't have a power rail of -5V in my circuit I used the LM2776 charge pump to obtain it using the +5V power rail available in my circuit. The LM2776 is not outputting the -5V that I was hoping for. The output is -1.76V it is...
