Abstract

PURPOSE:To increase the delay time and to produce a sure power-on reset signal, by selecting that the ratio of channel length to width of FETs constituting inverters can be smaller than that constituting an external circuit. CONSTITUTION:The ratio, W/L, of channel width W to channel length L of each FET constituting a C-MOS inverter is made remarkably small and the output characteristics can be mitigated. Thus, the circuit power supply reaches already a specified level +VDD at t5 after the period T when the output of the final stage of FET45 rises, allowing sure reset.
