摘要： In one example, a high-speed divider (38) includes two identical pseudo-CML latches (L1, L2) and four output inverters (70-73). Each latch includes a pair of cross-coupled signal holding transistors (MN1, MN2, MN7, MN8). A first P-channel pull-up circuit (MP1, MP3) pulls up on a second output node QB of the latch. A second P-channel pull-up circuit (MP2, MP4) pulls up on a first output node Q of the latch. A pull-down circuit (MN3-5, MN9-11) involves four N-channel transistors. This pull-down circuit: 1) couples the QB node to ground when a clock signal CK is high and a data signal D is high, 2) couples the Q node to ground when CK is high and D is low, 3) prevents a transfer of charge between the QB and Q nodes through the pull-down circuit when D transitions during a time period when CK is low, and 4) decouples the QB and Q nodes from the pull-down circuit when CK is low.

摘要： A reconfigurable filter circuit has a first path including a transimpedance amplifier (TIA). The transimpedance amplifier has an input that receives an input current and an output that outputs a voltage. The reconfigurable filter circuit also includes a switchable feedback path. The switchable feedback path includes a first low-pass filter coupled to an output of the TIA. The switchable feedback path also includes a first switch to couple the feedback path to provide a feedback current to the first path resulting in a bandpass response in the output voltage when the switch is closed and a low-pass response in the output voltage when the switch is open.
