Title: Driver circuit
Inventor: EMA NOBUAKI
IPC: H03K17/66
Filed: 1990-01-12
Abstract: PURPOSE:To increase the amplitude of an output voltage by constituting a differential switch with 1st, 2nd, and 3rd, 4th differential TRs and giving an output switching signal to each base of 2nd and 4th and 3rd and 5th differential TRs respectively in in-phase and giving it between the groups in opposite phase. CONSTITUTION:When differential TRs 3, 6 are turned on by an output voltage switching signal, a current from a current source 2 all flows from the differential TR 3 to a reference voltage source 1 and does not flow to a load resistor 9. An extraction current of a current source 7 is all supplied from the differential TR 6 through a resistor 8 and the load resistor 9. When the differential TRs 4, 5 are turned on, the current supplied from the current source 2 is branched from the differential TR 4 to the resistor 8 and the load resistor 9. The extracted current from the current source 7 is supplied from the reference voltage source 1 by the differential TR 5 and does not flow to the load resistor 9. Thus, an output voltage being twice more than a conventional circuit is obtained with a high speed TR with a comparatively small current capacity.
