نویسندگان
چکیده
Design techniques for robust, low-power CMOS circuits are presented for applications in wireless cubicmillimeter sensor nodes. First, the design of a two-transistor voltage reference is described and its characteristics simulated. Then, a low-voltage toggle flip-flop circuit is discussed and modeled using standard switching theory. Finally, a study of the battery used to power the cubic-millimeter system is detailed.

A fast low-power 1-bit full adder circuit suitable for nano-scale CMOS implementation is presented. Out of the three modules in a common full-adder circuit, we have replaced one with a new design, and optimized another one, all with the goal to reduce the static power consumption. The design has been simulated and evaluated using the 65 nm PTM models.
