A 92-mu W/Gbps Self-Biased SLVS Receiver for MIPI D-PHY Applications

Abstract

This brief introduces a self-biased Scalable Low-Voltage Signaling (SLVS) receiver circuit in order to minimize the power dissipation on D-PHY layer of the Mobile Industry Processor Interface (MIPI). This design does not require any static bias circuitry. It can also support an input common-mode voltage of the receiver as low as 50 mV. This allows D-PHY transmitter to use lower common-mode voltage further reducing the power dissipation of the transceiver pair of D-PHY layer. It is fabricated in a 180-nm CMOS process. The test results show that it operates up to 2 Gbps at 1.2 V power supply in High Speed-mode (HS-mode) of MIPI D-PHY standard. The power efficiency is 92 μW /Gbps or 77 μA /Gbps.
