Introduction to Electronic Circuits Chapter 5 Bi-polar Junction Transistor"1.8V/5.0V CMOS, BJT, diode, resistor, capacitor, and EEPROM are summarized in Table 1. 1.8V/5.0V CMOS is fully compatible with an industry standard 0.18um logic process. III. KEY DEVICE CHARACTERISTICS A. HVMOS Transistors Fig. 2 shows the schematic cross section of the key devices in the aBCD1840 process. In the aBCD1840 process,It asks to build the small signal model of a PNP transistor circuit. When I checked the proposed solution, I was a bit confused. Following are the original circuit and the proposed small-signal model. My confusion is that, this is a PNP transistor, so the current flows from the emitter to the base and to the collector, unlike an NPN transistor.

Depletion Layer BJT NPN Dengan adanya konstruksi BJT yang disusun sedemikianrupa seperti ditunjukan Gambar 4 bahwa elektron dapat melewati atau berpindah dari derah N ke P melalui junction karena terdapat perbedaan konsentrasi elektron pada masing-masing daerah.Proses perpindahan elektron melalui junction disebut sebagai …The BJT is formed by two p-n junction (either npn or pnp ), so at a first glance it's symmetrical. But both the concentration of dopant and the size of the regions (and more important: the area of the junctions) is different for the three regions. So it simply won't work at the full potential. (like using a reversed lever) ….
