Title: Auto abstraction method for small-signal model of hetero junction bipolar transistor
Inventor: RYU GI HYEON
IPC: H01L29/73
Filed: 2002-04-23
Abstract: PURPOSE: A method for automatically abstracting a small signal model of a hetero-junction bipolar transistor(HBT) is provided to abstract each element value of a small signal equivalent circuit by calculating a precise value regarding each capacitance between a base and a collector of the HBT. CONSTITUTION: A base resistance value is determined from a real part of the first operation formula of a Y parameter. A capacitance value is determined from an imaginary part of the first operation formula. The sum of two capacitances between the base and the collector in a low frequency region of the Y parameter. A capacitance value between the base and the collector is determined in a high frequency region of the Y parameter. A gain value is determined from the second operation formula of the Y parameter. The capacitance between the collector and an emitter is determined from the third operation formula of the Y parameter. The abovementioned processes are repeated until a difference between the result value and a measurement value falls within an error scope.

Title: Digital audio apparatus and radio broadcast receiving method thereof
Inventor: CHO NAM GYU
IPC: H04N5/44
Filed: 2002-04-26
Abstract: PURPOSE: A digital audio system and a radio broadcasting receiving method of the system are provided to add a radio receiving function to the digital audio system without increasing the volume of the audio system. CONSTITUTION: A digital audio system includes an internal memory(12), a D/A converter(18), a socket(14) into which an external card is inserted, an amplifier(21), and a controller(11). The internal memory records coded digital audio data in case of recording, reads the digital audio data in case of reproduction, and erases the digital audio data in case of erasure. The D/A converter decodes the coded digital audio data in the event of reproduction and converts the decoded data into an analog signal. The amplifier amplifies the signal output from the D/A converter and, when the external card is a radio tuner card, amplifies the signal output from the socket. The controller judges whether or not the external card is the radio tuner card and, when the external card is the radio tuner card, transmits a broadcasting signal from the radio tuner card to the socket in case of broadcasting signal hearing mode. The controller blocks signal transmission between the radio tuner card and the socket in case of a digital audio related mode.
