Abstract: PURPOSE:To attain miniaturization, high performance and low power consumption by using a combination of shift registers, capacitors and transistors(TRs), and imparting the charge stored in the capacitor to other capacitors in terms of capacitance. CONSTITUTION:Registers 1, 8 generate output pulses S11-S16 and S21-S26 sequentially every time a clock is fed to terminals 3, 10 after a start pulse is fed to terminals 2, 9. An input signal from the terminal 4 passes any of write TRs 15-20 selected by the pulses S11-S16 and stored in one of capacitors (C) 66-71. Then an 'H' level is fed to a terminal P1 at a TV synchronization horizontal period, a signal stored in the C66-71 passes through transfer TRs 27-32 and is divided in the C72-77 in terms of the capacitance. Then driving pulses P2, P3 and a clock CLK 2 are supplied to read the charge of the C66-71 and the charge in the C72-77 is read at the succeeding blanking period. Thus, the same signal is outputted over a 2H period, and the delay is implemented with miniaturization, high performance and low power consumption.
