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. ...
