Abstract: One embodiment is a reconfigurable mixer topology for selectively implementing one of a harmonic rejection mixer (HRM) and a subharmonic mixer (SHM), the reconfigurable mixer topology comprising a mixer core comprising a plurality of differential mixers each having a first clock input and a second clock input; a clock generator for generating a plurality of clock signals each having a different phase; and a clock distributor for distributing the plurality of clock signals to the first and second clock inputs of the differential mixers in accordance with a designated operation of the reconfigurable mixer as an HRM or an SHM.

Abstract: Herein disclosed are systems and circuitry for protecting against overdrive and electrostatic discharge. For example, protection circuitry may include field effect transistors to discharge overdrive outside of an operational voltage range of a circuit in some embodiments to prevent damage to the circuit. Further, the protection circuitry may utilize diode features inherent in the field effect transistors to protect against electrostatic discharge in some embodiments. The circuitry may be implemented in radio frequency sampling analog-to-digital converters and can provide for single-ended signal input and/or output for the analog-to-digital converters.

Abstract: An ultra-wideband distributed ADC can be cascaded to build high performance radio frequency (RF) analog electronics integrated with advanced digital complementary metal-oxide-semiconductor (CMOS) electronics on the same wafer. Advantages can include wide spectral coverage, high resolution, large dynamic range, and high information processing bandwidth. Part of an overall system includes a precise, programmable, real-time delay circuit that can achieve picosecond accuracy.

Abstract: Various approaches to implementing digital loopback in a radio frequency (RF) system are disclosed. An example RF system includes a receiver that includes an ADC and a transmitter that includes a DAC. The apparatus includes multiple digital loopback circuits provided at different points between the digital domain processing of the receiver and the transmitter. Each digital loopback circuit may include a combiner and one or more weighing circuits, which make the circuit programmable. The combiner of a given digital loopback circuit is configured to combine a RX signal and a TX signal at a particular point of the digital domain processing of the receiver and the transmitter where said digital loopback circuit is implemented. The one or more weighting circuits are configured to define the how much of the TX signal and/or RX signal is used for said combination.
