Webby the energy required to charge the MOSFET gate. That is, the Q G(TOT) at the gate voltage of the circuit. These are both turn-on and turn-off gate losses. Most of the power is in the MOSFET gate ... WebA voltage reference circuit provides a reference voltage in response to a programmed threshold voltage of a first non-volatile memory (NVM) transistor. The threshold voltage of the first NVM transistor is programmed by applying a programming voltage to commonly connected source/drain regions of a tunneling capacitor, which shares a floating gate …
