why it needs a transistor?

In this article, we’ll take a look at the Analog Devices AD5758, which is a single-channel DAC with dynamic power control and HART connectivity.

This article describes superposition and its simple applications.

An analysis of the concepts and variables associated with state-space, canonical and system transfer function representations of the common converters. In direct circuit linearization averaging technique, dynamic behavior of the circuit cannot be studied at the resonant frequency as the switching frequency component of the output for the resonant converter is different from the local average value frequency. Thus, the integral expression of the average value needs to be extended using the Fourier series; and the derivative expression with respect to a particular frequency is required for the dynamic analysis.
