Part I: Structured Mixed-Mode Design Johan H. Huijsing In order to shorten the design time of integrated circuits, industry has a general need to automate the design flow. The fifth paper discusses a structured simulation-based analog design synthesis. Fig.4 shows an architecture like this. It is possible to derive a stable pulse from a first-order oscillator by observing the integrator output signal by means of a comparator and compare it to a reference level, not being one of the reference levels at which the memory of the oscillator switches. 3.2. Second-order oscillators In second-order oscillators both time constants play an equally dominant role. We know nothing about our starting circuit other than acceptable numerical ranges for ...
