Voltage comparator using unequal gate width FET's |
摘要 |
The threshold comparator includes a switching FET including a gate electrode and a load FET connected in series across a source of potential where the load FET is configured to provide a saturation current less than that of the switching FET with a first input level to the gate electrode and provide a saturation current greater than that of the switching FET with a second input level to the gate electrode. The output voltage of the switching FET changes value abruptly when the input level at its gate electrode attains the second input level where the saturation current in the switching FET is less than the saturation current of the load FET.
