Triangular Waveform Generation using Mixed Signal Modeling

Abstract

The development of modeling languages such as Verilog-HDL and Verilog-AMS allows the behavior of analogue and mixed signal circuits to be described with a more lucid way as compared to the conventional circuit-level simulators. Mixed-signal simulators are thus providing a new platform for more efficient modeling of mixed signal that contains both the analogue and discrete features which was not previously possible. The non-linear characteristics of many circuits are still difficult to be exactly described by the conventional simulators. Hence it is required to explore the simulation behavior of analogue and mixed-signal circuits in a more efficient manner which can be done using mixed signal modeling languages. This paper presents an alternative approach to model the behavior of analogue and mixed-signal circuits based upon piecewise linear waveforms. A triangular waveform generator is modeled using the mixed signal modeling. The proposed model of triangular waveform generator can be used in the circuits for signal processing. The triangular-wave generator is often necessary in laboratories for efficient generation of other types of fixed periodic functions. It is also useful for performance testing of electrical network and servo-systems. The waveform generator modeled using mixed-signal modeling provides more accurate and highly precise waveform which reflects its advantages.
