Abstract

A clock distribution network includes receiving a remote voltage signal; transmitting the remote voltage signal into a local voltage signal using a current-mode transmission scheme that comprises a cascade of a voltage-to-current driver, a transmission line, a current buffer, and a LC (inductor-capacitor) tank; transmitting the local voltage signal into a first destination voltage signal using a voltage-mode transmission scheme that comprises a cascade of a first capacitively driven wire and a first inverter buffer; and transmitting the local voltage signal into a second destination voltage signal using a voltage-mode transmission scheme that comprises a cascade of a second capacitively driven wire and a second inverter buffer.
