UA46501U - Microelectronic device for determination of diffusion length of minor carriers in semiconductors - Google Patents

Abstract

The invention proposes a microelectronic device intended for determination of diffusion length of minor carriers in semiconductors, in which a signal processing and indication unit, a microelectronic frequency converter including a first and second resistors, a first and second field-effect transistors, an inductance, a capacitor and a first and second DC voltage source are incorporated. A first pole the first DC voltage source is connected to gate of the first field-effect transistor, source of which is connected to first lead of the inductance, to upper contact of the first resistor and to gate of the second field-effect transistor, to which a first output terminal of the microelectronic frequency converter circuit is connected, drain of the first field-effect transistor is connected to drain of the second field-effect transistor, to low contact of the first resistor and to upper contact of the second resistor, second lead of the inductance is connected to first lead of the capacitor and to the first pole of the second DC voltage source. A second pole is connected to second lead of the capacitor and to second terminal of the first DC voltage source, source of second field-effect transistor and to low contact of a second resistor which form a common bus to which second output terminal of the device is connected, to output terminals the signal processing and indication unit is connected..
