摘要： Systems and methods for reducing variability in the output impedance of an integrated switch-mode power amplifier (PA) split the output impedance between passive resistor, which may be on-chip, and a MOSFET switch of the amplifier. The PA may have a single-ended configuration or a differential configuration having two single-ended structures operating with opposite phases. In one implementation, the size of the MOSFET switch is larger than that of the MOSFET switch implemented in a conventional PA, but the size is still acceptable to operate the PA at a desired frequency. In addition, a calibration approach may be utilized to ensure that the MOSFET switch has a controlled and calibrated ON resistance, thereby providing stable output power levels of the PA and ensuring consistency and repeatability in NMR measurements.

摘要： An analog belief propagation system uses current mode implementations of storage elements and circuit implementations of at least some nodes of a factor graph using current representations. The system mitigates or avoids effects of non-linearities and approximations in storage and processing elements of the system, for instance, by using storage cells that reproduce current values and using factor circuits that separate control sections and signal path sections of the circuits.

摘要： An approach to converting an analog value based on a partition of an input range produces probabilities that the input is found within each of the regions based, for example, on a noisy version of the input. In some examples, iterative and/or pipelined application of comparison circuitry is used to accumulate a set of analog representations of the output probabilities. The circuitry can be adapted or configured according to the characteristics of the degradation (e.g., according to the variance of an additive noise) and/or prior information about the distribution of the clean input (e.g., a distribution over a discrete set of exemplar values, uniformly distributed etc.).

摘要： An approach for accurately setting a duty cycle of PA switching waveforms uses an all-digital PVT sensor circuit. In various embodiments, the all-digital PVT sensor circuit measures a pulse width of a periodic reference signal using digital delay line, and subsequently, implements an off-chip digital calculation to program the digital delay line to delay this periodic reference signal so that, when the delayed periodic reference signal is combined with the original (undelayed) reference via a logical AND operation, the resulting signal conforms to a desired duty cycle. In one implementation, the PA is a class-D PA, which may have a single-ended configuration or a differential configuration having two single-ended structures operating in opposite phases.

摘要： A storage device includes a storage array having a group of storage elements. Each storage element can written to a discrete set of physical states. A read circuit selects one or more storage elements and generates, for each selected storage element, an analog signal representative of the physical state of the selected storage element. A signal processing circuit processes the analog signal to generate a plurality of outputs, with each output representing a degree of an association of the selected storage element with a different subset of one or more of the discrete set of physical states.

摘要： Various approaches of adjusting a gain of received signals in integrated circuitry include implementing an open-loop source-degenerated amplifier having a pair of input devices for amplifying the received signals; boosting an effective transconductance of the input devices (e.g., using a pair of super-gm feedback loops); and setting a bias current of devices in the open-loop source-degenerated amplifier (e.g., using a constant-gm bias circuit.)
