WebDCAP= statement in a BJT model by including DCAP= in the BJT’s .MODEL statement. Convergence Adding a base, collector, and emitter resistance to the BJT model improves its convergence. The resistors limit the current in the device so that the forward-biased pn junctions are not overdriven. Table 14-1: BJT Options capacitance DCAP ...

WebJan 9, 2011 · Yes, there are applications. A BJT in common emitter configuration can be used as analog switch (C-E is switched), e.g. for choppers or synchronous demodulators. Unfortunately, it has a DC offset voltage of 2 to 20 mV in on-state (Vce,sat @ Ic = 0). In inverse mode, the offset voltage (Vec,sat @ Ie = 0) is only 0.05 to 0.5 mV. WebProcedure: The ALM1000 hardware power supply limits the maximum voltage available to 5 volts. The emitter base reverse breakdown voltage of many transistors is larger than this. In the configuration shown, voltages between 4.5 volts and 9.5 volts ( CA- V peak to peak swing + external battery voltage ) can be measured.
WebJunction Breakdown - BJT has two diodes back-to-back. Each diode has a breakdown. The diode (BE) with higher doping concentrations has the lower breakdown voltage (5 to 10 V). In forward active region, BC junction is reverse biased. In cut-off region, BE and BC are both reverse biased. The transistor must withstand these reverse bias voltages.
