    Abstract: Systems, methods, and devices provide sampling for data converters. Methods include receiving a voltage from a voltage source, and identifying transconductance parameters and resistance parameters associated with a data converter, the transconductance parameters identifying a transconductance of the data converter. Methods also include selecting a resistor from a plurality of dynamically selectable resistors based on the resistance parameters, generating, using a programmable gain amplifier, a current based, at least in part, on the selected resistor and the received voltage, and providing the current to the data converter.

    Abstract: Hybrid analog-digital processing systems are described. An example of a hybrid analog-digital processing system includes photonic accelerator configured to perform matrix-vector multiplication using light. The photonic accelerator exhibits a frequency response having a first bandwidth (e.g., less than 3 GHz). The hybrid analog-digital processing system further includes a plurality of analog-to-digital converters (ADCs) coupled to the photonic accelerator, and a plurality of digital equalizers coupled to the plurality of ADCs, wherein the digital equalizers are configured to set a frequency response of the hybrid analog-digital processing system to a second bandwidth greater than the first bandwidth.

    Abstract: Herein disclosed are multiple embodiments of a signal-processing circuit that may be utilized in various circuits, including conversion circuitry. The signal-processing circuit may receive an input and produce charges on multiple different capacitors during different phases of operation based on the input. The charges stored on two or more of the multiple different capacitors may be utilized for producing an output of the signal-processing circuit, such as by combing the charges stored on two or more of the multiple different capacitors. Utilizing the charges on the multiple different capacitors may provide for a high level of accuracy and robustness to variations of environmental factors, and/or a low noise level and power consumption when producing the output.

    Abstract: A filter circuitry (200) using an active inductor is disclosed. The filter circuitry (200) has a first terminal (In1/Out1) and a second terminal (In2/Out2). The filter circuitry (200) comprises a first transistor (M1) and a second transistor (M2). The filter circuitry (200) further comprises a first switch (S1), a second switch (S2), a first capacitor (C1), a second capacitor (C2) and a resistor (R). The first and second transistors (M1/M2) together with the resistor (R) and the first and second switches (S1/S2) are connected in a current mirror topology. The first and second capacitors (C1/C2) are connected at the first and second terminals of the filter circuitry (200) respectively. The filter circuitry (200) is configurable to either have the first terminal (In1/Out1) as input and the second terminal (In2/Out2) as output or have the first terminal (In1/Out1) as output and the second terminal (In2/Out2) as input by changing on-off states of the first and second switches. The transistors are interconnected in a current-mirror fashion. Depending on the switch position one of the transistors also acts as part of an active inductor such that the circuit functions as a low pass filter with a complex pole pair and a real pole. Depending on the switch position the LPF allows signal flow in either direction. For use in a TDD environment in combination with a passive mixer (420).

    Abstract: A wireless access point apparatus includes a mixer, an analog low-pass filter (ALPF), an analog-to-digital converter (ADC), a radar detector and a controller. The mixer is configured to mix a wireless signal and a carrier signal for performing frequency conversion on the wireless signal. The ALPF with a passband is configured to perform filtering on the wireless signal, so as to filter out a signal component of the wireless signal out of the passband. The ADC is configured to convert the wireless signal from an analog form to a digital form. The radar detector is configured to detector whether the wireless signal includes any radar signal. The controller is configured to adjust a carrier frequency of the carrier signal depending on a determination result of the radar detector for switching between a dynamic frequency selection (DFS) channel, a non-DFS channel and a composite channel.
