Reduced voltage subLVDS receiver |
摘要 |
A rail-to-rail high speed subLVDS receiver demonstrates good jitter and duty cycle performance for high-speed signals at low power supply levels. A sample receiver includes a voltage shifter for shifting the voltage levels of a differential input signal so that a shifted differential input signal is produced. The shifted differential input signal can be applied to a first differential pair, and the differential input signal can be applied to a second differential pair. The outputs of the first and second differential pairs can be summed together to produce a differential output signal. The differential output signal can be output using an output block. A clamp circuit can be used to adjust the gain of the first differential pair responsive to a common mode voltage of the first and second differential input signals.
