(Phasor notations are used assuming sinusoidal voltage input). The ac equivalent circuit is shown in fig. The h-parameters are assumed to be constant over the operating range. R S is the source resistance and Z L is the load impedance. 1 and to bias the transistor properly.Ĭonsider the two-port network of CE amplifier.

To form a transistor amplifier it is only necessary to connect an external load and signal source as indicated in fig.

100 topologies will be enough for simple switching circuits that use simple models only.ANALYSIS OF A TRANSISTOR AMPLIFIER USING H-PARAMETERS:

A total of no more than 100 new topologies.

Each time-varying source requires one state.

A total of no more than six logic gates.Įach PWL element requires one state.

A total of no more than six switches, simple or transistor.

A total of no more than 10 capacitors or inductors combined.

Source requires one state variable, with the exception of SINusoidal orĬOSinusoidal sources, which require two state variables per source. A capacitor or an inductorĮach requires one state variable.

A total of no more than 15 state variables.

The exact limits for the SIMPLIS simulator are: Will always have a number of internal nodes depending on complexity. The node count includes all circuit nodes and some of these may be internal to device models.

140 analog nodes (internal and external - see note below).

The exact limits for the SIMetrix simulator are: There is a limit to the size of circuit that can be simulated. User scripts can be enabled for 30 days using the unlock feature.

Safe Operating Area testing is not available.

Verilog-HDL mixed signal simulation is not available.

The Verilog-A compiler is not available.

The command line is not present, preventing any features that require the command line.

You are welcome to use SIMetrix/SIMPLIS Elements as a free general purpose schematic drawing tool. There are also no limits on the size of schematic that can be drawn, saved or printed. There are no limits on the complexity of arbitrary source expressions or arbitrary logic block definitions.
