This paper presents a systematic methodology for developing structural macromodels expressing the linear and weakly nonlinear performance of analog circuits. The models are in the frequency domain. The methodology includes two steps. First, building-block behavioral (BBB) concept is used to describe the basic building blocks of a circuit, and a decoupling technique is used to generate uncoupled BBB...
The design of reconfigurable DeltaSigma modulators requires cumbersome circuit-level simulations. Besides the challenges inherent to high-performance analog-to-digital converter (ADC) design, the gap between system-level specification and circuit-level implementation makes the design even more difficult and inefficient. Circuit macromodels are an efficient way of tackling these problems by speeding...
This paper presents a systematic methodology for developing structural nonlinear macromodels for analog circuits. The methodology includes two steps: first, a nonlinear system is represented as a system with nonlinear inputs and linearly coupled blocks. Then, the linear couplings are removed. The methodology also uses description of circuit nonlinearities as a successive composition of three operators...
