Title: Delay circuit
Inventor: OKADA YASUYUKI
IPC: H03K5/133
Filed: 1987-04-14
Abstract: PURPOSE:To output a delayed pulse by selecting properly the ratio of a gate width and a gate length of a MOS transistor(TR) so as to prolong the charging time of a capacitor and shorten the discharge time. CONSTITUTION:The ratio of the gate width and the gate length of a TR Q1 of a logic gate comprising TRs Q1, Q2 is decreased more than that of the TR Q2. Thus, the time charging a capacitor C1 is made longer and the discharge time is shorter to quicken a P-channel TR Q3 to be turned on and to retard the rise in the gate potential of an N-channel TR Q4. Thus, the input clock signal is retarded.
