Abstract

Engineering Engineering, Electrical & Electronic Science & Technology Technology
In this paper, the first comprehensive methodology is presented for design of low power adiabatic circuits inclusive of the adiabatic core design and the power-clock generation. Prior works have focused on either designing adiabatic cores or the power clock generation circuit, only. These non-comprehensive views can misrepresent the performance savings and fail to address the opportunities at integration. In this work, a comprehensive solution is presented that also features a unique innovation for the power clock generation circuit in step-charged circuits designed with rotary traveling wave oscillators (RTWO) and adiabatic frequency dividers. In experimentation, SPICE based simulations are performed at 416MHz and 330MHz in the 90nm technology node and compared to CMOS based implementations, as well as other known power-clock generation techniques. A 32-bit CMOS adder consumes 3.5x more power when compared to the proposed 32-bit ECRL adder operating at a frequency of 416MHz. Furthermore, 1000 32-bit CMOS adders in parallel consumes 3.4x more power when compared to 1000 32-bit ECRL adders in parallel designed with the proposed architecture at a frequency of 416MHz
