Title: Hysteresis circuit
Inventor: UNO YOSHIFUMI
IPC: H03K17/687
Filed: 1983-06-23
Abstract: PURPOSE:To make a high-speed operation possible and reduce the dependence upon voltage by driving an FET, which is operated as a feedback element, with the output, which is obtained by inverting amplification of the output of an amplifying circuit in the input stage, to reduce the channel width of this FET. CONSTITUTION:If an input voltage VIN is lower than a threshold voltage VT, FETs 22 and 23 are turned off, and consequently, an output VOUT becomes low, and an FET24 is turned off. If the input voltabe VIN is equal to or higher than the threshold voltage VT, the FET23 is turned on, and a potential V26 becomes low. According as the input voltage VIN rises, a potential V25 falls in accordance with on-state resistances of FETs 21, 22, and 23, and the output VOUT becomes high, and the FET24 is turned on. If the voltage VIN is switched from the high level to the low level, the potential V25 rises because a ratio of the on-state resistance of the FET21 to the synthetic on-state resistance of FETs 22-24 is high, and the output VOUT becomes low, and a hysteresis is obtained. The channel width of the FET22 is made narrow and channel widths of FETs 23 and 24 are made wide for the purpose of getting a wide hysteresis width, and thus, a high-speed operation is possible.

CONSTITUTION:An N epitaxial layer laid upon a P type substrate and including an N<+> buried layer is separated by 104 and an N<+> connecting layer 105 is formed. After coating SiO2 106 and Si3N4 107 thereon, ions are selectively injected to form P<+> layers 106 and 108. Then, PSG110 and Si3N4 111 are laid upon by turns and a resist mask 112 is applied thereon. By etching them successively to expose SiO2 106 and removing it with use of a mixture of NH4F and acetic acid, there are formed visors at the Si3N4 film 111. The mask 112 is removed and an N<+> layer is selectively formed by ion-injecting under an anotehr mask. Then, Al 117 is evaporated. Finally, predetermined electrodes 118 are formed by solving the PSG110 to eliminate it. According to this method, connecting holes and the wirings can be formed through the self-alignment by only one number of matching of the mask and further the wirings properly connected to the diffusion layer can be obtained with high degree of integration.
