摘要： The disclosure relates to an alternating current (AC) coupling circuit including first and second capacitors having first and second input terminals configured to receive an input differential signal and generate an output differential signal at first and second output terminals of the first and second capacitors. The AC coupling circuit further includes a baseline wander correction circuit configured to make the output differential signal resistant to baseline wander due to the input differential signal including one or more time intervals of unbalanced data. The baseline wander correction circuit includes a differential difference amplifier (DDA) having a first differential input configured to receive the input differential signal, a differential output configured to generate a compensation differential signal, and a second differential input configured to receive the compensation differential signal. The compensation differential signal is applied to the output terminals of the first and second capacitors via a pair of resistors, respectively.

摘要： The disclosure relates to a system and method for controlling a common mode voltage of an output differential signal of a differential signal processing circuit. The differential signal processing circuit includes two load devices (RL1, RL2), two input transistors (M11, M12), and two current-source transistors (M21, M22) coupled in series between voltage rails, respectively.

The common mode voltage (VICM) of the input differential signal is applied to the replica input transistor (M1 R ) to generate a replica output common mode voltage. A feedback circuit generates a bias voltage for the replica current-source transistor (M2 R ) and the current-source transistors (M21, M22) of the differential circuit to control the output common mode voltage of the replica circuit and the differential signal processing circuit.

摘要： An apparatus and method for generating a temperature-compensated reference voltage are disclosed. The apparatus generates substantially equal temperature-compensated currents by controlling (through negative feedback) voltages across separate resistors through which the currents flow, respectively. Two of the temperature-compensated currents are formed by combining (e.g., summing) a complementary to absolute temperature (CTAT) current (ICTAT) and a proportional to absolute temperature (PTAT) current (IPTAT). A reference voltage VREF is produced by configuring the other the temperature-compensated current to flow through an output resistor.
