Low power current mode receiver with inductive input impedance

Abstract

In this paper we show that current mode signaling system with receivers using inductive input impedance can provide a low power solution to high speed data transmission over long lines. We show that beta multiplier circuits can be designed such that they exhibit inductive input impedance and their use as current mode receivers provides significant enhancement in data rates. Simulation results show that it is possible to transmit data at eight times higher data rates than voltage mode with an one order of magnitude lower power consumption. Even compared to other current mode signaling systems, those using receiver with inductive input impedance show around 50% improvement in data rate at marginally lower power consumption.
