MOSFET Gate Threshold
N-Channel MOSFETs require an enhancement voltage
greater than its source voltage. Typical N-Channel
MOSFETs have a gate-source threshold (V
higher. Since the source of the high side N-Channel
MOSFET is connected to V
requires a voltage greater than the V
example, our SSTL_2 termination circuit has a V
