Abstract
Software-programmable analog computing is pro-
posed for power- and area-efficient acceleration of computa-
tional electromagnetics. All-pass filters are employed to realize a
continuous-time finite-difference time-domain (FDTD) algorithm.
A CMOS realization of an analog computer (AC) that solves the
1-D wave equation using this time-continuous FDTD algorithm
at an equivalent temporal update rate of 625 MHz is reported
(180-nm CMOS, chip area of 4 mm
2, supply voltage = 1.8V ,
and power = 200 mW).
