DC Bias Point Analysis

Abstract

When you connect a battery or a power supply to a circuit, the circuit voltages and currents effectively settle down to what is known as a DC steady-state condition. This is also known as the operating point or Bias Point of a circuit under steady-state conditions. In PSpice, the Bias Point analysis calculates the node voltages and currents through the devices in the circuit. For example, for a simple common emitter transistor amplifier, the Bias Point analysis will calculate the base, emitter, and collector bias voltages and the base, collector, and emitter quiescent currents.
