Abstract: Certain aspects of the present disclosure provide methods and apparatus for calibrating a transceiver for wireless communications. One example method generally includes configuring a first oscillating signal as an input signal to at least a portion of a receiver (RX) path, calibrating a residual sideband (RSB) of the receiver path using a second oscillating signal as a local oscillating signal for the receiver path, and calibrating an RSB of a transmitter (TX) path by routing an output of the transmitter path to the receiver path, after calibrating the RSB of the receiver path. Another example method generally includes routing an output of a transmitter path to a receiver path, using a first local oscillating signal for the transmitter path, using a second local oscillating signal for the receiver path, and measuring an output of the receiver path as a local oscillator (LO) leakage for the transmitter path.

Abstract: 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.
