Abstract

The concept of programmable switched-current floating-gate (PSIFG) cells is presented. A floating-gate current mirror provides programmability while a switched current element offers discrete time operation within the analogue domain. The concept is demonstrated by a circuit that implements a second-order FIR filter with arbitrary, programmable coefficients. For this system, simulated results show a power consumption of 1 μW with a 1V supply voltage.
