On the implementation of PFSCL serializer

This paper proposes the implementation of a serializer in positive feedback source-coupled logic (PFSCL) style. Two realizations for the PFSCL serializer are put forward. The first one is based on the conventional NOR based approach while the fundamental cell based approach is applied in the second one. The functionality of the proposed serializers based on the two approaches is verified through SPICE simulations using TSMC 0.18 μm CMOS technology parameters. A comparison in the performance of the two PFSCL serializers is also drawn. It is found that the fundamental cell based serializer outperforms the NOR based serializer.
