Abstract

This chapter describes a number of general applications suitable for quantifying the requirements of universal active devices or Operational Amplifiers. The transfer of each example is described by a matrix containing, firstly, one or more nominal values, and secondly, error terms having low values. The nominal values are determined by the circuit configuration and by the gain-setting passive components in the circuit. The error terms are determined by the non-idealities of the active devices as discussed in Chapter 2. Each of the error terms can be relatively easily expressed as a sum of errors caused by:
  • firstly, the non-zero input voltage;

  • secondly, the non-zero input current;

  • thirdly, if the input port is floating, the CM input current; and

  • fourthly, if the output port is floating, the non-zero CM output current.
