摘要： A signal transfer circuit for dynamic action with boot strap effect is formed with an inputting transistor Tr.sub.11 and a driving transistor Tr.sub.12 for driving a load Z.sub.1. To a gate electrode of a resetting transistor Tr.sub.13, a positive voltage V.sub.1 and a negative voltage V.sub.2 are alternately applied at 50% of duty ratio in synchronism with a shift pulse by transistors Tr.sub.15 and Tr.sub.16 connected in series between the positive voltage V.sub.1 and the negative voltage V.sub.2 and pulses .PHI..sub.1R and .PHI..sub.2R which are synchronous with shift pulses .PHI..sub.1 and .PHI..sub.2. When an output Q.sub.1 is HIGH level, a transistor Tr.sub.14 becomes conductive to force a gate voltage of the transistor Tr.sub.13 to 0 to release resetting.
