A Wi-Fi security authentication method and a communication apparatus are disclosed. In the method, an access point (AP) receives a first access request from a supplicant, where the first access request carries a first parameter, and the first parameter is a parameter generated by the supplicant based on a generator of a cyclic group and a first random number; generates a second random number, generates a second parameter based on the second random number and the generator of the cyclic group, and sends the second parameter to the supplicant; generates a second pairwise master key based on the second random number, the first parameter, the second parameter, and a first target random key; and performs a four-way handshake authentication procedure with the supplicant based on the first pairwise master key and the second pairwise master key.

A method for offset cancellation in a receiver loss of signal (RxLOS) circuit of a serializer/deserializer (SerDes) receiver device includes receiving a differential input signal via the first stage of a peak detector cell of the RxLOS circuit and shorting the differential output of the first stage via a control switch of the second stage of the RxLOS circuit. The control switch may further transition the RxLOS circuit from normal operating mode to an offset cancellation mode wherein the control switch may manually or automatically short the differential output of the first stage.

Simplified and effective offset calibration circuit for RxLOS in serdes

A coupling apparatus having plurality of branches and a resistive element is disclosed. Each branch may be configured to couple at least one of (i) a first input node and (ii) a second input node to a first output node through a plurality of switches and a plurality of capacitors. The resistive element generally connects the first output node to a second output node. The first output node may be loaded by a respective parasitic capacitance of at least one of the switches.

AC coupling circuit with hybrid switches and constant load

A coupling apparatus having a first branch and a second branch is disclosed. The first branch generally comprises (A) a first switch group configured to connect an input signal to an output node through a first capacitor, and (B) second switch group configured to connect either (i) a second signal, or (ii) a ground voltage, to the output node through a second capacitor. The second branch generally comprises (A) a third switch group configured to connect the input signal to the output node through a third capacitor, and (B) a fourth switch group configured to connect either (i) the second signal, or (ii) the ground voltage, to the output node through a fourth capacitor.
