  • Overdrive electrostatic discharge clamp
    Patent number: 11916376
    Abstract: An electrostatic discharge clamp is shown, which includes a clamping circuit, a driving circuit, a capacitor and resistor network, and a bias circuit. The clamping circuit has a plurality of transistors connected in a cascode configuration. The driving circuit is coupled to the gates of the transistors of the clamping circuit. The capacitor and resistor network introduces an RC delay in response to an electrostatic discharge event to control the driving circuit to turn on the transistors of the clamping circuit for electrostatic discharging. The bias circuit biases the driving circuit to turn off the transistors of the clamping circuit when the capacitor and resistor network does not detect the electrostatic discharge event.

  • Leftover bits processing for proportional round-robin resource unit parsing in extreme high-throughput systems
    Patent number: 11916846
    Abstract: A method pertaining to leftover bits processing for proportional round-robin resource unit (RU) parsing in extreme high-throughput (EHT) systems involves processing a stream of bits to provide processed bits. The method also involves transmitting the processed bits to a station (STA) over a combination of multiple resource units (RUs) assigned to the STA. In processing the stream of bits, the method may involve parsing the stream of bits to the combination of multiple RUs. Moreover, in an event of leftover bits remaining from the parsing, the method may further involve distributing the leftover bits to one or more RUs but not all RUs of the combination of multiple RUs.
