Louis P. AlarcÓn

Sense Amplifier-based Pass Transistor Logic (SAPTL)

Advisor: Prof. Jan M. Rabaey

The SAPTL is an alternative circuit topology that allows the reduction of energy per operation via voltage scaling even in the presence of leakage. It allows aggressive threshold voltage scaling since the V_th of the stack transistors can now be decoupled with its subthreshold leakage, allowing for very low threshold voltages and thus allowing the stack transistors to remain in the superthreshold region. In addition, the differential signaling used by the SAPTL lends itself to synchronous and asynchronous operation and the inherent layout regularity points to the SAPTL as a very good candidate for robust ultra low energy operation.
