Abstract: PURPOSE:To thicken the depletion layer of the periphery of a first semiconductor region and increase junction breakdown strength, and to improve the electrical characteristics of a semiconductor integrated circuit device by forming a second semiconductor region at a specified distance from the first semiconductor region. CONSTITUTION:A first semiconductor region 4 is brought into contact with a semiconductor substrate 1 having low impurity concentration or a third semiconductor region 7A by shaping a second semiconductor region 7B while being separated from the first semiconductor region 4 or forming the third semiconductor region 7A having the same conductivity type as the second semiconductor region 7B and impurity concentration lower than the region 7B between the first semiconductor region 4 and the second semiconductor region 7B, thus thickening a depletion layer in the periphery of the first semiconductor layer 4, then increasing junction breakdown strength. Accordingly, leakage currents flowing from the first semiconductor region 4 to the semiconductor substrate 1 are reduced, thus improving the electrical characteristics of a semiconductor integrated circuit device.

Title: Differential amplifier circuit
Inventor: HAYASHI SHIGEYOSHI
IPC: H03F3/45
Filed: 1993-04-02
Abstract: PURPOSE:To reduce the offset between inputs of a differential amplifier by detecting the voltage difference generated between input parts of a transistor TR differential pair and adding or subtracting a current corresponding to this voltage difference to or from the operating current of the differential pair. CONSTITUTION:A differential amplifier 2 provided with a TR differential pair 24 and a current cancelling circuit 14 are provided. If there is a variance among constant currents of respective current sources individually connected to TRs constituting the TR differential pair 24, a voltage difference corresponding to the variance current is generated between terminals of the resistor connecting the emitters of TRs and appears as the offset between bases of the TR differential pair. Then, the current cancelling circuit 14 detects the voltage difference generated between electrodes, namely, bases of TRs constituting the TR differential pair and supplies a current corresponding to this voltage difference to the differential pair to cancel the current which brings about the voltage difference, thus reducing the offset generated in the differential amplifier.

Abstract: PURPOSE:To set automatically a transmission output to an optimum value by discriminating an incoming level by an output of a squelch function in a radio equipment of simplex system so as to decide automatically the transmission output corresponding to an incoming output. CONSTITUTION:A noise level is a level of an output for operating squelch of a voice amplifier section 7 and nearly inversely proportional to the incoming level. A point (x) of the incoming level is taken as a threshold value of a level discriminating section and the transmission output is brought into a low output (position in dotted lines of switches SW2', SW3') or a high output (position in solid lines) depending whether the incoming level is higher or lower than the point (x). The level discriminating section 9 outputs a high or a low level voltage depending whether the incoming level is higher or lower than the threshold value (x), the voltage is stored in a voltage storage section 10 and an output of a current amplifier section 11 controls the SW2' and SW3' as above depending on this voltage. Further, the voltage storage section 10 holds the said voltage during transmission and clears the holding voltage when the section 10 is brought into the receiving state by a control signal for changing over the transmission and reception and repeats the operation above depending on the incoming level of the reception state.
