WebFeb 4, 2024 · Introduction. A transistor latch is a circuit which latches ON with a permanent high output in response to a momentary input high signal, and continues to stay in this position as long as its in the powered condition, regardless of the input signal. A latch circuit can be used to lock or latch the output of the circuit in response to an input ... WebThe net result is a rectangular drive voltage waveform at the internal gate-source terminals of the MOSFET 10. For ideal compensation of inductance L2, the gate time constant T g and the source time constant T s are set to be equal: T s =T g =R1×L1=R2×L2. The current gain, G, of the switch is: G =Isource/Igate=R1/R2=L1/L2.
