Abstract: Apparatus and methods for rotary traveling wave oscillators (RTWOs) are provided herein. In certain configurations, an RTWO includes a differential transmission line connected in a ring and a plurality of segments distributed around the ring. The segments include metal stubs extending from the RTWO's differential transmission line. The metal stubs aid in providing access to additional layout resources for tuning capacitors and other circuitry of the RTWO's segments, while permitting the length of RTWO's ring to be relative short. Thus, the metal stubs do not inhibit the RTWO from operating with relatively high oscillation frequency, while providing connectivity to tuning capacitors that tune the RTWO's oscillation frequency over a wide tuning range and/or provide fine frequency step size.

Abstract: Apparatus and methods for frequency tuning of rotary traveling wave oscillators (RTWOs) are provided herein. In certain configurations, distributed quantized tuning is used to tune a frequency of the RTWO. The RTWO includes a plurality of segments distributed around the RTWO's ring, and the segments include tuning capacitors and other circuitry. The distributed quantized frequency tuning is used to control the tuning capacitors in the RTWO's segments using separately controllable code values, thereby enhancing the RTWO's frequency step size or resolution. Moreover, in configurations including multiple RTWO rings that are locked to one another to reduce phase noise, the distributed quantized frequency tuning can be used to separately set the tuning capacitors across multiple RTWO rings that are coupled to one another.

Abstract: A bias-shaping circuit for adjusting power consumption in a frequency divider to a temperature-dependent minimum includes a temperature-dependent bias source for producing a temperature-dependent bias. The bias is combined with an input signal to create an output bias. The output bias changes in response to a change in temperature to compensate for at least a portion of a temperature-induced change in the frequency divider, thereby adjusting power consumption in the frequency divider to a temperature-dependent minimum.

Abstract: One aspect of this disclosure is an apparatus including an oscillator that includes a secondary LC circuit to increase a tuning range of the oscillator and/or to reduce a phase noise of the oscillator. Another aspect of this disclosure is an apparatus that includes oscillator with a primary LC circuit and a secondary LC circuit. This oscillator can operate in a primary oscillation mode or a secondary oscillation mode, depending on whether oscillation is set by the primary LC circuit or the secondary LC circuit.

Abstract: Aspects of this disclosure relate to a segmented receiver for a wireless communication system. The segmented receiver includes a first receiver segment and a second receiver segment configured to receive respective radio frequency signals. The radio frequency signals can be orthogonally polarized. Branch circuits in each receiver segment can provide a radio frequency signal to different mixers. The different mixers can be included in different receiver segments and receive local oscillator signals from independent local oscillators. Each receiver segment can process a different bandwidth of the radio frequency signal. Two different bandwidths of the radio frequency signal can be processed concurrently by different receiver segments.
