Patent TW-390018-B (TW)
Title: Semiconductor integrated circuit
Inventor: YAMAGAMI TOSHINOBU
IPC: G01R31/30
Filed: 1998-06-25
Granted: 2000-05-11
Abstract: The objective of the present invention is to generate different internal power supply voltages with each other at the time of an accelerated test and a non-accelerated test in a semiconductor integrated circuit having an inner step-down circuit. A semiconductor integrated circuit has such a first voltage characteristic I that in the case where an external power supply voltage VEXT is in a range from a given value V1 to a given value V2, it has little dependence on an internal power supply voltage VINT while keeping a preset voltage VA. If the external power supply voltage VEXT exceeds the given value V2, at the time of a non-accelerated test (at the time of a working margin confirmation test), the circuit exhibits a second voltage characteristic II that is varied from the preset voltage VA depending on the internal power supply voltage. At the time of an accelerated test, a third voltage characteristic III is developed wherein a voltage is varied from a preset voltage value VB, which is higher than the preset voltage VA depending on the internal power supply voltage. Accordingly, at the time of the working margin confirmation test, the internal power supply voltage VINT is continued by virtue of the characteristics I, II, making it possible to guarantee the operation within the voltage range from VA to VB. At the time of the accelerated test, satisfactory voltage acceleration is obtained with the aid of the characteristic III.

Title: Testing circuit capable of measuring the capacitance of the electronic phone in the client circuit
Inventor: WANG JIAN-SHUEN
IPC: H04M3/22
Filed: 1999-04-02
Granted: 2002-10-11
Abstract: A testing circuit capable of measuring the capacitance of the electronic phone in the client circuit is disclosed, which is applied in the testing of the electronic phone in the client circuit. It is found that the traditional phone and the modern electronic phone are different in the testing process, since the modern electronic phone utilizes IC chips to form the circuit for driving the speaker and generating ring sound. To prevent the erroneous operation and protect the chip, a high voltage Zener diode is added to achieve the purpose. For the convenience of testing the inner blocking capacitance of the electronic phone, a high voltage (above 96V) is applied to charge the phone in the client circuit, and high and low triggering voltage level are set. The high and low triggering voltage level discharging time can thus be accurately determined by the interrupt function and counting function of microprocessor. From the computation of circuit theory, the capacitance can be obtained to know if the phone exists.

Abstract: A method and system for providing suppression of near-end speech energy for tone signal detectors. In accordance with the invention a system or device is connected between the tip and ring on a subscriber loop, the subscriber loop being connected to office equipment and that subscriber's station set. The system also includes a receive interface that is connected to either a tone signal detector or a frequency shift keying modulator. The system achieves speech cancellation by forming a Wheatstone bridge with a mirror circuit possessing a scaled image of the loop and office equipment impedance. In one embodiment of the invention the Wheatstone bridge is formed using the combined impedance of the loop and office equipment as the impedance that is to be matched by a set of balanced networks included within the system. In accordance with this aspect of the invention the Wheatstone bridge uses a parallel circuit with common end nodes containing two known resistances of equal value that are singularly connected to the unknown impedance and the matched impedance, respectively. Voltage division occurs across each circuit. When the unknown impedance is perfectly matched the voltage and signal phase in each circuit is the same. In another embodiment of the invention the resistances are replaced by using an active component. Specifically, a transistor pair is configured as mirrored current sources.
