In a diode model two diodes are connected back-to-back to make a PNP or NPN bipolar junction transistor (BJT) equivalent. This model is theoretical and qualitative. This model is theoretical and qualitative.
A schematic diagram of the Ebers-Moll models of a PNP BJT. The base, collector and emitter currents are I B, I C and I E, the common-base forward and reverse current gains are α F and α R, and the collector and emitter diode currents are I CD and I ED.

For each solution to PnP, the chosen point correspondences cannot be colinear. In addition, PnP can have multiple solutions, and choosing a particular solution would require post-processing of the solution set. RANSAC is also commonly used with a PnP method to make the solution robust to outliers in the set of point correspondences. P3P methods ...
The connections are illustrated in the adjacent diagram. Because the p-type material is now connected to the negative terminal of the power supply, the ' holes ' in the p-type material are pulled away from the junction, leaving behind charged ions and causing the width of the depletion region to increase.
A curve tracer is a specialised piece of electronic test equipment used to analyze the characteristics of discrete electronic components, such as diodes, transistors, thyristors, and vacuum tubes. The device contains voltage and current sources that can be used to stimulate the device under test (DUT).
An IGBT cell is constructed similarly to an n-channel vertical-construction power MOSFET, except the n+ drain is replaced with a p+ collector layer, thus forming a vertical PNP bipolar junction transistor. This additional p+ region creates a cascade connection of a PNP bipolar junction transistor with the surface n-channel MOSFET. The whole ...
Fluxgate sensors or saturable inductor current sensors work on the same measurement principle as Hall-effect-based current sensors: the magnetic field created by the primary current to be measured is detected by a specific sensing element. The design of the saturable inductor current sensor is similar to that of a closed-loop Hall-effect ...
Capacitive sensors are constructed from many different media, such as copper, indium tin oxide (ITO) and printed ink. Copper capacitive sensors can be implemented on standard FR4 PCBs as well as on flexible material. ITO allows the capacitive sensor to be up to 90% transparent (for one layer solutions, such as touch phone screens).
