Title: Semiconductor device
Inventor: KAWAJIRI YOSHIKI
IPC: H03K5/08
Filed: 1988-04-08
Abstract: PURPOSE:To charge and discharge a load capacity with an arbitrary constant current specified beforehand and to realize a low transient current without being dependent on the manufacturing dispersion, etc., by making a current mirror circuit controlled by an input pulse into a load driving circuit. CONSTITUTION:A current mirror circuit is controlled by one type of inverters compound of transistors(TR)Q1 and Q2. When the TRQ2 is on and the TRQ1 is off, the current mirror circuit is formed between a TRQ3 and a constant current source S and an output driving TRQD, and when the TRQ2 is off and the TRQ1 is on, the TRQD is off. Here, when the current input of the current source S in the mirror circuit is i/n, the gate width of MOST is w/n and the gate width of the TRQD is (w), the on current of TRQD becomes a constant current (i). Consequently, even when a gate width (w), a gate length or the threshold voltage of the TR are changed by the dispersion of the manufacturing process and the i/n is constant, the driving current of the QD becomes approximately constant and the low transient current of charging a sense amplifier SA, etc., can be executed.

Abstract: PURPOSE:To remove the termination of a mishievous call by receiving and discriminating the voice of a calling subscriber by a called subscriber's circuit and generating a call tone from a called subscriber's telephone set only to the termination from a suitable subscriber. CONSTITUTION:A terminating signal from a calling subscriber 14 arrives at a called subscriber's telephone set connecting terminal 9 from an exchange 11 through a telephone line 10. Consequently, a call signal receiving circuit 1 is driven, a circuit 2 for selecting a voice or a pulse signal is driven by an output of the circuit 1 and a DC loop of the telephone line is held to form the call waiting state of the calling subscriber. When a voice or a signal is generated from the calling subscriber, a signal storage circuit 3 collates whether the voice or the signal is the already registered signal or not, and only when the voice or signal is the registered signal, sends its output to a switching circuit 5. The circuit 5 informs the termination to the telephone circuit and the DC calling circuit loop is formed on the basis of a called subscriber's answer. Conse quently, the termination of a mishievous call can be removed.
