Abstract : In the dc analysis of a circuit the capacitors and inductors in the circuit are replaced by open and short circuits, respectively, and the circuit is solved for constant source values (all time-varying signal sources are set to zero). In the analysis and design of electronic circuits the dc solution is called the quiescent, bias or operating point of the circuit and has many uses. For example, the operation of most electronic circuits is critically dependent on the quiescent point and it is important to know its value and its sensitivity with respect to parameter changes such as temperature, etc. In small signal analysis the quiescent point should be determined in order to calculate accurate small signal models. Finally, in transient analysis the initial states of the capacitors and inductors must be known, and this is accomplished by dc analysis. (Author)
