Abstract	This paper presents a methodology for high-level synthesis of continuous-time linear analog systems. Synthesis results are architectures of op-amps, sized resistors and capacitors such that their ac behavior and total silicon area are optimized. Bounds for op-amp dc gain, unity-gain frequency, input, and output impedances are found as a byproduct of synthesis. Subsequently, a circuit synthesis tool can be used to synthesize the op-amps of an architecture. The paper details the architecture generation technique. Architecture generation produces alternative architectures for a system specification using the tabu search heuristic. Its main advantages over traditional methods is that it is application independent, does not require a library of block connection patterns, and is simple to implement. The paper also discusses the hierarchical, two-step parameter optimization that guides architecture generation. Experiments showed that linear analog systems operating at low/medium frequencies (like telecommunication systems and filters) can be synthesized in a reasonably long time and with reduced effort.
