sTransistor is a productivity utility to aid in biasing transistor amplifier configurations. It enables the user to choose between twelve of the most common bipolar transistor bias configurations and then calculate a bias resistor network for support the chosen transistor bias. The transistor small signal "h" parameters are supported and can be changed to support a specific transistor. In addition, bias stiffness for those bias configurations which provide a sufficient degree of freedom can be modified.

Release notes:
UPDATE:
Version 2.0 includes the following changes:
   • The number of bias circuits has increased from 12 to 20.
   • Contrast between dark and light modes has been improved
   • Greater control over emitter stabilized bias circuits has been implemented
   • Numerous bugs and failures have been corrected.
