The yield of adiabatic circuits strongly depends on the effects of parameter variations on the power dissipation. The dispersion of the threshold voltage has the most important impact on the yield. Different effects on the energy consumption due to interdie and intra-die variations of the threshold voltage are presented. Three logic families, the Efficient Charge Recovery Logic (ECRL), the Posi...

A model of autonomous logic nets composed of n threshold elements is presented and several properties of a single threshold element are generalized to this model. The number of these nets is shown to be 2kn (-<k<l) for completely specified machines. The capacity of the net is defined and conjectured to be 2, similar to the case of a single threshold element.

2. CAPACITIVE SOLUTIONS This paper reviews differential implementations of threshold logic gates, detailing two classes of solutions: capacitive (switched capacitor and floating gate), and conductance/current. The concept underlying capacitive TLGs is the use of an array of capacitors to implement the weighted sum of inputs. The idea was introduced as early as 1966 [6]. Capacitive TLGs can be c...

Near threshold circuits (NTC) are an attractive and promising technology that provides significant power savings with some delay penalty. The combination of NTC technology with MOS current mode logic (MCML) is examined in this work. By combining MCML with NTC, the constant power consumption of MCML is reduced to leakage power levels that can be tolerated in certain modern applications. Addition...

This paper deals with a new method for implementing Binary Adders of two operands whose main characteristics are: They are built using only threshold gates; carry output, besides carry input, is used to obtain each sum bit and the total number of gates is a linear function of the number of bits of the operands (n).
