(5) УСТРОЙСТВО ДЛЯ ИЗМЕРЕНИЯ КОЭФФИЦИЕНТА УСИЛЕНИЯ ПО ТОКУ ТРАНЗИСТОРОВ(5) DEVICE FOR MEASURING THE GAIN COEFFICIENT ON TRANSISTOR CURRENT
1one
Изобретение относитс к измерительной технике и предназначено дл контрол параметров полупроводниковых приборов, в частности дл измерени коэффициента усилени по току транзисторов, при их массовом производстве .The invention relates to a measurement technique and is intended to control the parameters of semiconductor devices, in particular for measuring the current gain of transistors, during their mass production.
Известно устройство дл измерени статического коэффициента усилени по току транзисторов, содержащее источник эмиттерного тока, источник коллекторного напр жени , переключатель рода работ, усилитель и измерительный блок l.A device for measuring the static current gain of transistors is known, comprising an emitter current source, a collector voltage source, a type of work switch, an amplifier, and a measuring unit l.
Недостатком известного устройства вл етс наличие систематической погрешности, обусловленной конечной величиной сопротивлени резистора, включенного в базовую цепь испытуемого транзистора. Другим недостатком устройства вл етс низка производительность, обусловленна необходимостью переключени измерительного устройства (вольтметра ) с коллекторной цепи на базовую в процессе контрол .A disadvantage of the known device is the presence of a systematic error due to the finite value of the resistance of the resistor included in the base circuit of the tested transistor. Another disadvantage of the device is the low productivity due to the necessity of switching the measuring device (voltmeter) from the collector circuit to the base one during the control process.
Известно также устройство дл измерени коэффициента усилени поIt is also known a device for measuring the gain factor
J /току транзисторов ). содержащее источник эмиттерного тока и коллекторного напр жени , резисторы , вольтметр и генератор синусом дальнего напр жени 2.J / current transistors). containing a source of emitter current and a collector voltage, resistors, a voltmeter, and a generator with a sine of a far voltage 2.
IQ Недостатком известного устройства вл етс наличие систематической погрешности, обусловленной конечной величиной сопротивлени резистора, включающего в базовую цепь испытуе15 мого транзистора, низка производительность , обусловленна большим временем измерени напр жени с помощью вольтметра.IQ. A disadvantage of the known device is the presence of a systematic error due to the finite resistance value of the resistor including the test transistor in the base circuit, low productivity due to the long voltage measurement time with a voltmeter.
