Abstract: An analog-to-digital converter (ADC) includes a first comparator, a second comparator, and a decision timing comparison logic unit. The first comparator is configured to output a first output voltage and the second comparator is configured to output a second output voltage during a same binary algorithmic iteration of the ADC. The decision timing comparison logic unit is configured to identify a first polarity of the first output voltage and a second polarity of the second output voltage and, if the first polarity is equivalent to a second polarity, to insert at least one redundant capacitor for a next binary algorithmic iteration of the ADC.

Abstract: A method is provided. A first edge on a first gating signal is generated, and a local oscillator and a shared clocking circuit with the first edge on the first gating signal. A second edge on a second gating signal is generated following the first edge on the first gating signal, and a receiver circuit is activated with the second edge on the second gating signal, where the receiver circuit includes a mixer. A transmit pulse following the first edge on the first gating signal is generated with the transmit pulse having a third edge. A switch that short circuits outputs of the mixer is then released following the later of the third edge of the transmit pulse and a delay.

Abstract: An amplifier includes a graphene Hall sensor (GHS). The GHS includes a graphene layer formed above a substrate, a dielectric structure formed above a channel portion of the graphene layer, and a conductive gate structure formed above at least a portion of the dielectric structure above the channel portion of the graphene layer for applying a gate voltage. The GHS also includes first and second conductive excitation contact structures coupled with corresponding first and second excitation portions of the graphene layer for applying at least one of the following to the channel portion of the graphene layer: a bias voltage; and a bias current. The GHS further includes first and second conductive sense contact structures coupled with corresponding first and second sense portions of the graphene layer. The amplifier also includes a current sense amplifier (CSA) coupled to the GHS. The CSA senses current output from the GHS.
