Title: Multiple transmission output circuit
Inventor: SAKURAI SHIGEMI
Filed: 1984-09-25
Abstract: PURPOSE:To reduce noises generated from a transmission line conductor by multiple transmission by dividing a transmission signal into a positive-phase signal and a negative-phase signal, converting each signal into a trapezoidal wave respectively to drive four output transistors (TRs) with a single power supply. CONSTITUTION:A signal generating circuit LG inputs a rectangular wave pulse signal X to output signals Y1, Y4 of the same phase as that of the signal X and signals Y2, Y3 of opposite phase. The signals Y1, Y4 are inputted to an inverted trapezoidal wave converting circuit SU2 and the signals Y2,Y3 are inputted to a non-inverting trapezoidal wave converting circuit SU1 respectively. The output of the circuit SU2 is inputted to TRs Q13,Q43 whose electrodes are connected te a power supply V1 and ground GND to change the impedance for the trapezoidal wave. Further, the output of the circuit SU1 is inputted to TRs Q33,Q23 whose electrodes are connected to the power supply V1 and GND to change the impedance for the inverted trapezoidal waveform to the Q13,Q43. The other electrodes of the TR Q13,Q43 are connected in common to form a load connecting terminal PL and the other electrodes of the TR Q33, Q23 are connected in common to form a load connecting terminal PR, and a load ZL connected between the PL and PR is driven.
