Abstract
This paper describes a single-chip analog computer for solving the one dimensional (1-D) wave equation. The chip integrates a 16-point discrete-time but continuous-valued finite-difference solver with spatially-programmable wave velocity, selectable boundary conditions, and arbitrary input excitation waveforms. Built-in Δ-Σ analog-to-digital converters (ADCs) allow the solution results to be easily read out by a digital processor. The design was realized in TSMC 180 nm CMOS and has an active area of 2.81 mm × 2.64 mm. Experimental results prove the functionality of the proposed analog solver.
