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: Certain aspects of the present disclosure provide methods and apparatus for generating a two-tone signal for performing linearity calibration of a radio frequency (RF) circuit. One example apparatus generally includes a tone generating circuit configured to generate a first single-tone signal from a digital clock signal and a mixer connected with the tone generating circuit and configured to mix the first single-tone signal with a second single-tone signal to provide a two-tone signal having frequencies at a sum and a difference of frequencies of the first and second single-tone signals.

Abstract: An amplifier includes a gain transistor including a control terminal to receive an input signal. A degeneration inductor is coupled between the first terminal of the gain transistor and ground. A shunt inductor and a capacitor are coupled in series between the control terminal of the gain transistor and ground, and form a filter to attenuate frequencies of the input signal within a frequency range. The degeneration inductor and the shunt inductor form a transformer to provide impedance matching.

Abstract: Systems, apparatus and methods in a mobile device to multiplex two global navigation satellite system (GNSS) signals on a single hardware receiver chain are presented. The GNSS signals may come from a common GNSS system on two bands of two different GNSS systems overlapping on a common band. A duty cycle of the GNSS signals may be based on a harmonic being within one of the first band and the second band. The duty cycle may be based on signal quality, such as indicating a jammed or non jammed signal. The duty cycle may be of unequal proportions and less than 100% such that the receiver chain is idle for a percentage of time.
