摘要:
A quasi-static level shifter includes an output stage including a first transistor which is controlled directly by the input signal, and a further transistor connected in series with the first transistor to terminals of a DC supply voltage and which is controlled, via a capacitance, by the input signal combined with a recurrent, spike-shaped signal. The level shifter thus behaves as a static level shifter but has a lower current consumption and requires less surface area.
