In a normal silicon diode at rated currents the arbitrary cut in voltage is defined as 06 to 07 volts. Note that the germanium diode has a forward voltage of less than 200mv whereas the bogus germanium transistors have vbe of over 650mv.ĭoes anyone have the spice model for the 1n270 germanium diode. We will endeavor to accommodate spice model requests when possible for inclusion into our website spice model inventory. The value is different for other diode types schottky diodes can be rated as low as 02 v germanium diodes 025 to 03 v and red or blue light emitting diodes leds can have values of 14 v and 40 v respectively. Hello everyone i am trying to simulate the germainium diode characteristics in pspice. A google search didnt find it although i found a couple of postings where the author used a model for 1n270 so i think it must exist somewhere.

Download pspice lite for free and get all the cadence pspice models. At this point we can open the pspice model editor and click on new from menu file and then new from menu model.

Make the necessary rotations for the parts, and move the parts to appropriate locations. This article will provide you with a detailed introduction to the circuit diagram and show you how to make a circuit diagram with Edraw circuit diagram software. First insert all the parts without considering their values (for example, place a resistor without considering the resistance value of it, etc.). Table below lists the model parameters for some selected diodes. This can be divided into following substeps. Diodes incorporated is currently developing spice models for many of our products.Ĭadence pspice technology offers more than 33000 models covering various types of devices that are included in the pspice lite software. I have found several online libraries of spice models for diodes but none of them have the 1n270. Browse cadence pspice model library.Ĭonsult the manufacturers web site. I only have the free version of pspice and it does not have germanium diodes. A fallback strategy is to build a spice model from those parameters listed on the data sheet. Simulating a silicon diode with a dc sweep and plotting the graph is no problem. Here is the proof that someone posted a silicon transistor model. Does anyone have spice models for germanium transistors. Cadence pspice technology offers more than 33000 models covering various types of devices that are included in the pspice lite software. Germanium diodes vs schottky diodes for audio dist. The easiest approach to take for a spice model is the same as for a data sheet. zener voltage (X-axis).For eg we can assume the standard value of 11 ev while its 07 ev for schottky diode and 067 ev for germanium diodes.

The AMS Simulator window will render a plot of the zener current (Y-axis) vs. In the schematic capture window, press the keyboard's F11 key to run the selected PSpice simulation profile (which, presumably, is the DC Sweep simulation profile you just created). In the schematic capture window, save these changes to your project. In the schematic capture window, attach a Current Marker probe to the zener diode's cathode lead. These charts can seem overwhelming at first, but they're simpler to.

Click on OK to save these changes and close the Simulation Settings dialog. Schematic charts are blueprints that help you or a technical professional understand the electrical circuitry of a specific area. The Sweep Type is Linear with a Start Value of -1.5V, and End Value that is one or two volts greater than the zener voltage (e.g., if \$V_=6\$ choose an End Value of 7V), and an Increment value of 1mV. Select voltage source V1 as your Sweep Variable. In the schematic capture window, create a new simulation profile and select DC Sweep as the Analysis Type. Wire a ground reference (the '0' zero part) to the wire that connects V1's negative (-) terminal to the zener's anode. Wire V1's positive (+) terminal to the zener's cathode, and wire V1's negative (-) terminal to the zener's anode. For the sake of this discussion, I'll assume the VDC part's reference designation is V1. In the schematic capture window, place a VDC part in parallel with your zener diode.
