摘要： Low voltage differential signaling (LVDS) circuitry and method for dynamically controlling the common mode voltage at the input of an LVDS receiver. The common mode voltage of the incoming LVDS signal is monitored. The common mode voltage at the input of the LVDS receiver is clamped at a clamp voltage when the common mode voltage of the incoming LVDS signal is less than a predetermined voltage, and allowed to track it otherwise.

摘要： Circuitry and method for digital-to-analog current signal conversion with phase interpolation. For an n-bit digital-to-analog converter (DAC), the number 2n control bits normally required can be reduced to 2(n-1) by jointly controlling pairs of the current sources with one of the 2(n-1) current control bits and inverses of two other ones of the 2(n-1) current control bits.

摘要： Differential signal detection circuitry with an integrated reference voltage. The reference voltage is added as an offset to the output voltage, and its integration ensures that variations in the reference voltage closely track variations in the signal. Accordingly, the detection threshold for the signal being detected remains more consistent over variations in the circuit manufacturing process, power supply voltage and operating temperature.
