Summary: | Single-ended transceivers are mostly used for DRAM interfaces to reduce pin count. A low-supply transceiver is preferred, especially for mobile DRAM interfaces, for low-power consumption while maintaining a high-speed interface for transmission of image data [1]. To reduce transmitter power in single-ended transceivers, both the supply voltage and the signal swing are reduced: 0.8V and 200mV, or below [2]. However, with a small signal swing the low-supply voltage limits the maximum data rate that can be handled by the receiver (RX); the maximum data rate reported is below 10Gb/s with a supply voltage of 0.8V in 65nm CMOS [2-4]. In a conventional RX at a low-supply voltage, the maximum data rate is limited by the small g m /C of the RX front-end circuit. To eliminate this g m /C constraint, this work proposes a time-based RX for 12Gb/s operation at 0.8V. |
