Title: High breakdown strength integrated circuit
Inventor: FUJIHIRA TATSUHIKO
IPC: H01L27/02
Filed: 1991-11-29
Abstract: PURPOSE:To implement a low cost and a high reliability by providing at least one pair of low potential source lines, at least one pair of high potential source lines, a low potential circuit the power source of which depends on the low potential source line pair, and a high potential circuit the power source of which depends on the high potential source line pair. CONSTITUTION:A high potential power source VH comprises a P channel MOSFET P2 gate connected to a source line VHH on a low potential side, a depletion MOSFET ND2 to which a gate and a source are connected, and on the high potential side of which the low potential side of a Zener diode Z2 is connected. Therefore, the current flowing through the ND2 and a Zener diode Z1 generates a constant voltage at both ends of the Z2 with respect to the source lines on the high potential side of the VH connected to the terminal Vcc, thus making it possible to allow the lines connected to the source of the MOSFET P2 to become the low potential side source lines VHH of the high potential source line pair at any time. In this way, the area of the semiconductor substrate is made smaller, leading to cost reduction.

Title: Reference voltage generation circuit
Inventor: ITO YUJI
IPC: G11B7/135
Filed: 1987-12-16
Abstract: PURPOSE:To realize highly precise follow-up ability by generating a previously set reference voltage by an input signal containing an external factor, and generating automatically a variation corresponding to this factor. CONSTITUTION:A reference voltage generation circuit used for exposure position correction in an exposing process, i.e., one of the manufacturing process of an optical disk, is constituted of an operational amplification circuit consisting of operational amplifiers OP2-OP3, a variable resistor VR3 and resistors R8-R15. At that time, the resistance values between both ends of the resistors R8-R15 and the variable resistor VR3 are set at the equal value, and the resistance values of the resistors R12-R15 are set at the different equal value. Besides, the input signal Vin passes through the OP2, and generates signal voltages VA, VB through the resistors R8-R11 and the variable resistor VR3, and comes to be the reference voltage Vref by the differential amplifier OP3. Thus, even if the input voltage Vin varies, the correction following this variation is performed automatically, because the reference voltage Vref is determined unconditionally by the input voltage Vin.
