Abstract

This article proposes an interleaving switched- capacitor RF digital-to-analog converter (RFDAC) using an edge combiner within the output stage to implicitly triple its effective clock carrier frequency and enable the mm-wave (mmW) opera- tion. Tripling in the output stage allows for increased energy efficiency, which is further improved by employing an edge- combining-based frequency-tripling delay-locked loop (DLL) in the clock generation network. The clock tripling is performed in each slice o
