Behavioral elements are based on using an arbitrary algebraic equation as a transfer function to a voltage (E) or current (G) source. This function can include nodal voltages, element currents, time, or user defined parameters.

Arbitrary behavioral voltage or current sources (continued). o The following operations, grouped in order of precedence of B1 is a behavioral voltage source whose output voltage is equal to Vin * Iin. B5 and B2 produce voltages (P1 and P2) equal to the output powers of each regulator. B3 outputs a voltage equal to the function (100*(P1+P2)/Pin) - in other words the efficiency.

    Equations 6 and 7 describe the current source and sink behavior inside and outside the valid output voltage region. The internal V REF of any adjustable voltage reference is roughly 1.24V. Generated via bandgap reference, this specific voltage will ultimately define the limits of this topology overall. example on Chapter 2 material. Similarly, Example MS.5.2 refers to the second Multisim simulation example on Chapter 5 material. Besides the descriptions presented in this appendix, the reader will find the complete simulation files for each example on the book website. B.1 SPICE Device Models

Voltage and current output ABM sources are available. ABM (analog behavioral modeling) sources are much more powerful than linear or polynomial controlled sources because the controlling expression for ABMs is more arbitrary and easier to use.

    Using the "bi" and "bv" Arbitrary Sources in LTspice. The arbitrary sources in LTspice are incredibly versatile and useful. In the previous article it was shown how the "bi" source could be used to make a simple current dependent current source ("bv" could similarly be used to make a current dependent voltage source); however, the arbitrary sources can be used to create much more complex B1 is a behavioral voltage source whose output voltage is equal to Vin * Iin. B5 and B2 produce voltages (P1 and P2) equal to the output powers of each regulator. B3 outputs a voltage equal to the function (100*(P1+P2)/Pin) - in other words the efficiency.

    13/04/2016 · Nearly all circuits that you simulate need a voltage source of some kind. In LTspice, the humble voltage source rarely gets to demonstrate its true capabilities. This video will help you learn arbitrary meaning: 1. based on chance rather than being planned or based on reason: 2. using unlimited personal power…. Learn more. Learn more. Cambridge Dictionary +Plus

    The simplest way to implement it is using a \(G\) source (voltage controlled current source) or an \(R\) element. An alternative source would be a \(B\) (arbitrary behavioural voltage/current source) but you would then have to add labels or commands to identify the voltage/current that you want to use with it.
