ABSTRACT:
When a circuit that is likely to cause noise is enabled, a control circuit turns on a switch so that an inverter will be formed by one P-channel MOSFET and two parallel-connected N-channel MOSFETs. This helps enhance the current capacity of the inverter on its N-channel MOSFET side, and thereby lower the threshold voltage of the inverter.
