Acircuit-level design is implemented and expressed in terms of components, devices, and voltage–current relationships. the lowest level is device-level design, which involves selecting types of devices. before starting this level of design, you must have some knowledge of electronic devices and their characteristics, parameters, and models. as a part of this discussion, explain various steps involved in the design of a circuit to measure dc voltage in the range from 0 to 20 v. design specifications: for a full-scale deflection, the indicating meter draws 100μa at a voltage of 1 v across it. the current drawn from the dc supply should not exceed 1 ma. you may refer to the example 1.1 in the textbook to discuss the design process.
