Title: Signal delay device
Inventor: SAKAGUCHI TAKASHI
IPC: H04N9/64
Filed: 1993-09-17
Abstract: PURPOSE:To reduce the size and the cost of a signal delay device and to apply this device to various types of electronic devices by delaying and transmitting an input signal based on the resistance value set when a semiconductor element part conducts by the applied voltage and a time constant set by a capacitor. CONSTITUTION:The signal supplied to a terminal T$1 is delayed by a time proportional to the conduction (ON) resistance values of MOS type FETsM1-M3 and the time constant set by a capacitor C1 and transmitted through a terminal T2. Under such conditions, the ON resistance values of the FETsM1-M3 change when the voltage VB applied to a terminal T3 changes. In other wards, the delay time (delayed variable) can be changed when the input is transmitted through the terminal T2 since the time constant combined with the electrostatic capacity of the C1 changes. Therefore a circuit which can secure a prescribed delayed variable can be attained by a semiconductor integrated circuit that can be mass-produced. Then the signal delay circuit of the semiconductor integrated circuit can be applied to various types of electronic devices. Furthermore the size of the signal delay circuit can be reduced so that its installing area can also be reduced.
