Patent JP-H03167616-A (JP)
Title: Clock driver
Inventor: YAJIMA MASAKI
IPC: G06F1/06
Filed: 1989-11-28
Abstract: PURPOSE:To prevent the overlap of clock signal waveforms and at the same time to reduce the power consumption of a clock driver by providing a function which detects the non-overlap time of the output signal waveforms and switches the dimensions of the transistors of an output stage to each other in accordance with the detecting result of the non-overlap time of the output signal waveforms. CONSTITUTION:When two clock signals are outputted from a clock signal generating circuit 1, a NOR gate 2 detects the non-overlap period of both clock signals. When a proper non-overlap time is detected, a period when the outputs of both an inverter 3 and a delay circuit 4 are set at low levels at one time is detected. Then a high level emerges at the output of a NOR gate 5 and is latched by a latch circuit 6, and a multiplexer circuit 7 selects the output of the circuit 1 as it is. If the detected non-overlap time is not proper, a low level is latched by the circuit 6 and the circuit 7 selects the output sides of inverters 8 and 9. Thus it is possible to prevent the overlap of clock signal waveforms by increasing properly the driving capacity of both inverters 8 and 9.
