Abstract: Certain aspects of the present disclosure are generally directed to techniques and apparatus for adjusting capacitance in one or more metal-insulator-metal (MIM) capacitors in an effort to reduce capacitance variation between semiconductor devices and improve yield during fabrication. One example method for fabricating a semiconductor device generally includes measuring a capacitance value of a MIM capacitor of the semiconductor device, determining the measured capacitance value of the MIM capacitor is above a target capacitance value for the MIM capacitor, and selectively rupturing a set of connections in the MIM capacitor based on the measured capacitance value. Selectively rupturing the set of connections in the MIM capacitor may reduce the capacitance value of the MIM capacitor to a value approximately that of the target capacitance value.

Abstract: Power conservation in a radio frequency front end of a user equipment (UE) during wireless local area network (WLAN) communication is achieved by adjusting a power mode of the radio frequency front end. In one instance, the UE determines a signal strength of a received frame of a packet during a short training field of a preamble of the received frame. The determining occurs when a WLAN receiver is operating in a low power mode. The UE then switches the WLAN receiver to a high power mode during the short training field of the preamble or during a first segment of a long training field of the preamble when the signal strength is above a predetermined signal strength.
