FAST LOW POWER LEVEL SHIFTERS

摘要

In one embodiment, a method for increasing speed of a differential input pair (102), The method comprises applying a first boost current (M19 on) to a first input of the differential input pair during a transition of a first signal applied to the first input (INP); storing (C0) the first boost current; ending (M19 off) the application of the first boost current (V across C0) in response to the stored first boost current exceeding a first threshold (Vgs of M19); applying a second boost current (M20 on) to a second input of the differential input pair during a transition of a second signal applied to the second input (INN); storing (C1) the second boost current; and ending the application of the second boost current (M20 off) in response to the stored second boost current (V across C1) exceeding a second threshold (Vgs of M20).
