CMOS FET EQUATIONS by Preston Brown The following is a set of equations for CMOS field effect transistors. The constants included give a good approximation to common 1.6u processes. The models should be adjusted for your process This file may be downloaded directly into your HP-48GX. The equations contain process information: each equation uses its own Vt and K'. In addition the effective W and the effective L are calculated. For example in WNEQ 1.52 is subtracted from the width and 0.4 is subtracted from the length. The L effective and W effective terms assume the L and W are entered in microns.

Circuit Simulator v2.61 by Per Stenius A simple circuit simulator called Csim for the HP48. It makes DC, AC and transient simulations and supplies the user with all matrices used. The method used is modified nodal analysis, and thus elements such as an inductor or ideal voltage source require that a current branch is also specified together with the nodes.

Digital Logic Simulator by Tony Duell Here's a digital circuit simulator for the HP 48. It has 8 internal primitives: AND, OR, XOR, NOT, BUF (buffer), HI (node tied to logic 1), LO (node tied to logic 0) and CLK (clock generator of definable high and low times). It also supports nested macros defined from these elements.

Large Version by Larry Hoppis. The following HP48 program contains general 1% resistor utilities for electronics technicians and hobbyists. The main program 'RPAR' will find all combinations of parallel 1% resistors to obtain the desired value within a given accuracy. This is useful in case you don't have the value you need on hand, but also because the exact value you want may not be a standard off-the-shelf value.

RCC uses a graphical interface with very fast cursor selecting to let you choose the stripe colors of a resistor and will then display its value. It will also let you enter the numeric value of a resistor and will display the stripes the resistor should have.
