Title: Semiconductor integrated circuit device
Inventor: SUZUKI MAKOTO
IPC: H01L27/06
Filed: 1987-04-30
Abstract: PURPOSE:To speedup level conversion by providing a high speed logical circuit to handle a bipolar type signal, and executing the conversion to an MOS type signal level at the step of a bipolar type logical circuit. CONSTITUTION:Level converting circuits 203-206 impress an input signal to the source electrode of an MOSFET, change the current to flow at the MOSFET, detect the current, generate the same phase level-shifted signal, make two these same phase signals into the gate input signal of the MOSFET of a CMOS(composed of a PMOS120 and NMOS119), and convert the level. By the MOSFET of the CMOS constitution driven by a gate input signal, a bipolar transistor is further driven and the bipolar transistor drives a load. Thus, a single signal can be level-converted at the high speed and the load can be driven at the high speed. Thus, at the arbitrary position in a semiconductor integrated circuit in which an input buffer circuit 200 to receive a bipolar type input signal and an internal circuit to handle an MOS type signal are formed, high speed level conversion can be executed.

Filed: 1980-07-31
Abstract: PURPOSE:To increase the hightness of a displaying image and the picture quality, by supplying the output signal of an infrared ray detector to a differential amplifier directly and via a delay line and reversing the difference of both inputs in phase every prescribed time to obtain a video signal. CONSTITUTION:An infrared ray (a) radiated from a subject 1 of observation is switched with an infrared ray (b) radiated from a reference light source 4 in a prescribed period, and these rays are made incident to an infrared ray detector 5. The output signal of the detector 5 is branched to two lines, and one of these two lines is delayed 6 by a prescribed time to the other. Then both signals are supplied to a differential amplifier 7. The output of the amplifier 7 is supplied to the 2nd differential amplifier 8 via a siwtch S which is switched with every above-mentioned prescribed time. Then the video signal is extracted out of the amplifier 8. Thus the signal from which the correspondence component of radiation due to the radiation from a subject and given from the light source 4 is eliminated can be obtained for a time of about double as much as conventional. As a result, both the brightness of a display image and the picture quality are increased.
