Abstract:
1. An apparatus for outputting complementary signals, comprising: a differential logic block for performing a logic function in response to an input signal and outputting logic signals; a complementary output block comprising: a first output device and a second output device, each of which amplifies the logic signals from the differential logic block to provide the complementary signals; and a bootstrapping circuit connected in common to the first output device and the second output device and configured to apply a voltage higher than an input voltage to the complementary output block depending on the input signal, wherein the bootstrapping circuit block comprises: a first inverter and a second inverter for receiving the input signal, inverting the received input signal, and outputting a delayed input signal; a seventh transistor for receiving the delayed input signal of the first inverter and the second inverter; and a bootstrap capacitor connected to the seventh transistor.
