Abstract
PURPOSE:To attain high-speed operation by connecting a drive transistor(TR) and a load TR between a power supply and a ground potential in series and inputting an inverted signal at an output terminal to a gate of the load TR. CONSTITUTION:When an input goes to '1', the drive TR2 is turned on and its output is switched to a low level. In this case, the output of the inverting amplifier comprising TRs 3, 4 goes to '1' and an output current flows to a load TR. When the input goes to '0', the drive TR2 is turned off and the output of the logic circuit is shifted to a high level. When the level exceeds a logic threshold value when the inverting amplifier consisting of the TRs 3, 4 is viewed as an inverter exceeds a logical threshold value, the gate voltage of the load TR1 goes immediately to '0' and the current no longer flows. Thus, the ideal state is attained as the load characteristic and the switching speed is quickened further.
