Analog signal transmission circuit

Abstract

Abstract PURPOSE:To absorb the dispersion of the conduction resistance for each analog switch and thus to ensure the steady output impedance by inserting the voltage follower to the common transmission line after giving the common connection to the output terminals of the analog switch. CONSTITUTION:The output of OP amplifier 12 which is used as the pre-amplifier is sent to analog switch 6 and then to the common transmission line after giving the common connection to the output terminals of switches 6, 6 and so on. Then voltage follower circuit 24 comprising the OP amplidier is inserted to the common transmission line. Thus the dispersion of the conduction resistance can be absorbed for switches 6, and as a result the output impedance can be stabilized.
