Abstract

PURPOSE:To enable high speed of a voltage level converter, by determining the potential of each point through all common resistances, constant current and base- to-emitter forward voltage, by push-pull output type. CONSTITUTION:Although currents I22, I23 increase or decrease with input signals Vin, Vin', the current I25 is almost constant with the sum of the two. Further, constant currents I21, I24 are produced with an inverting operation transistor T26, and the amplitude is a half of the current I25. Further, potentials VB, VV at the points B and C are shifted by DELTAVinX1/2 by taking the voltage sum of VBE (VBE of transistor T23) and VBE' (VBE of transistor T26) according to the input signal Vin. Then, if Vin<Vin', Vc is high and VD (potential at point D) is low, causing a transistor T27 to be OFF. Further, if Vin>Vin', the state is inverse and the transistor T27 turns on. The turning on/off of the transistor T27 turns of/off the gate G of an I<2>L.
