Abstract :
In this paper we report on implementation considerations for second order FDSM analog-to-digital converters to be used in wireless sensor network nodes. A comprehensive Verilog-A simulation model is presented along with a new control logic. The allowed increase in power compared to first order converters is presented. Simulated results demonstrate the feasibility of a second order FDSM converter, and shows that 16 times increase in power compared to a first order FDSM converter is tolerated, while still maintaining the figure-of-merit.
