PURPOSE:To speed up the counter by the constitution that inversion circuits shifting signals through one phase clock pulse are in cascade connection. CONSTITUTION:A complementary MOSFET consisting of two series-connected pch type MOSFETs and two series-connected nch type MOSFETs, is used. A clock pluse is applied to one gate electrode of the pch and nch MOSFETs and the output of the preceding stage is applied to another gate. The inverter like this is in cascade connection by n stages to constitute the frequency circuit of 1/n. |
