Design of low power pulsed flip-flop using sleep transistor scheme

Ultra-low power m-sequence code generator for body sensor node applications

“…Therefore, an efficient FF design may significantly enhance the circuit power consumption. In literature, various circuits of D-FFs are proposed and investigated for low power application, each of which has its own pros and cons [18][19][20][21][22]. For comparison purposes, a performance analysis is carried out on several FF designs and presented in Tables 2-4.…”

“…Optimal D-FF designs must achieve a trade-off between the power consumption, the number of transistors (circuit size) and the perfor- [22] Failed Failed 104 150 TSPC [18] Failed at the required frequency CPEPTFF [22] Failed at the required frequency mance (delay) at ultra-low voltage supply. Therefore, the power delay product (PDP) based metric is used for comparative analysis and in particular for low power systems.…”

Subthreshold-based m-sequence code generator for ultra low-power body sensor nodes

“…In literature, various circuits of D-FFs are proposed and investigated for low power application, each of which has its own pros and cons [9], [10], [11], [12]. Optimal D-FF designs must achieve a trade-off between the number of transistors (circuit size) and the functionality at ultra low voltage supply.…”
