Title: Semiconductor device
Inventor: OKAMURA KENSHIRO
IPC: H01L29/72
Filed: 1986-02-08
Abstract: PURPOSE:To reduce the difference between each collector current caused by leak currents without increasing an area, by arranging a pattern in the manner in which the axis of symmetry of a PNP transistor is made parallel to the growth direction of an N-type buried layer. CONSTITUTION:The crystal growth direction of an N-type buried layer 90 and the axis of symmetry 12 of a PNP transistor are formed in paralleled with each other. In such a device, the positive hole density distribution in the base region 5 of a parasitic PNP transistor in the vertical direction becomes symmetric with respect to the axis of symmetry 12 of the PNP transistor. As the result thereof, the leak currents I3 and I5 become equal to each other, which flow from an emitter region 1 to a substrate 10 passing just under the respective collector regions 3a and 3b. Thus each of collector currents I1 and I2 becomes equal.

Title: Automatic gain control amplifier
Inventor: ITO HIROSHI
IPC: H03G3/20
Filed: 1986-02-07
Abstract: PURPOSE:To quicken the AGC control from the transmission to the reception by converting a peak value just before a reception signal disappears into a digital signal and holding the signal, selecting a DC potential of nearly the same level as the said holding signal and using it as a control signal in a time division 2-wire transmission system. CONSTITUTION:When a reception signal is fed to an input terminal 11, an AGC control voltage is fed to a terminal 13 by a peak value detection circuit 2. In such a case, a switch circuit 22 is thrown to the position (a). When the circuit 22 is thrown to the position (b) at the transmission, the peak value just before the mode changes from the reception to the transmission is converted into a digital signal in response to the amplitude by an A/D conversion circuit 3 and the result is held in a holding circuit 4. A control circuit 5 uses an output of the holding circuit 4 to control the switch circuit 21 and an AGC control voltage is fed to the terminal 13. The control voltage is a voltage being the division of the voltage fed between terminals 14, 15 by resistors, and a voltage close to the AGC control voltage just before the mode changes from the reception to the transmission is selected by the control voltage 5 and fed to the terminal 13.
