Patent JP-H10256890-A (JP)
Title: Logic circuit
Inventor: SESHIMO TOSHIKI
IPC: H03K17/693
Filed: 1997-03-11
Abstract: PROBLEM TO BE SOLVED: To provide a selector circuit in which a duty ratio of an output is not fluctuated even when DC offset levels of biphase input clock signals are deviated from each other. SOLUTION: Transistors(TRs) Q5, Q6 switch a current between differential pair TRs Q1, Q2 and differential pair TRs Q3, Q4 by using biphase clock signals CK, inverse of CK. A DC cut-off capacitor Cx is connected between sources of the TRs Q5, Q6 and the sources TRs Q5, Q6 are separated in terms of DC. Thus, a current flowing by two current source TRs Q10, Q11 is completely independent. Since the sources of the TRs Q5, Q6 are connected in terms of AC, a current switching function by the clock signal is active. Then even when the amplitude center of the biphase clock signals CK, inverse of CK is deviated, the duty ratio of an output signal of the selector circuit is not fluctuated thereby.
