摘要：

This paper describes a circuit theoretic formulation for simulating the Schrodinger equation using classical analog circuits. Update equations for a finite difference time domain (FDTD) Schrodinger equation solver with absorbing boundary conditions (ABCs) are used to derive signal flow graphs that naturally map to switched capacitor (SC) circuits. A prototype implementation of a fully-parallel SC FDTD solver with 128 spatial points and a clock frequency of 2 MHz is analyzed and simulated using a standard 180 nm CMOS process.
