Abstract: The present disclosure is generally directed to a method for driving an ultrasonic transducer. The method includes coupling a driving electrode and a ground electrode of the ultrasonic transducer to a power supply and a ground, respectively, during a first time period based on a received drive signal. The method further includes decoupling the driving electrode and the ground electrode of the ultrasonic transducer from the power supply and the ground, respectively, to float the driving electrode and the ground electrode of the ultrasonic transducer during a second time period based on the received drive signal to store a charge between the driving electrode to the ground electrode.

Abstract: The present disclosure is generally directed to an ultrasonic transducer interface system for use within portable 2-D ultrasonic imagers and includes an on-chip adaptive beamformer and Charge-Redistribution TX (CR-TX) to provide a drive strength of up to 500 pF/channel at 5 MHz (or 10 nF at 250 kHz) while reducing the TX drive power by at least 30% compared to other ultrasonic transducer TX drivers. The ultrasonic transducer interface system can be implemented in a single chip via, for example, a complementary metal oxide semiconductor (CMOS) process.

Abstract: Systems and methods for low-power single-wire communication are provided. In some embodiments, a method of operation of a transmitter to transmit a data word to a receiver using low-power single-wire communication includes receiving the data word to be transmitted to the receiver. The method also includes encoding the data word to be transmitted in a Pulsed Index Communication (PIC) format to produce a PIC data word and transmitting the PIC data word to the receiver. In this way, the transmitter may be able to transmit an increased amount of data while maintaining a simple communication protocol that uses low power and does not require a Clock-Data Recovery circuit.

Abstract: A SoC includes an AFE to receive a plurality of differential input channels and generate digitized data corresponding to the channels, and a classification processor configured to receive the digitized data from the AFE. The AFE includes a Dual-Channel Chopper to perform channel multiplexing of two channels while simultaneously chopping the channels, a Dual Channel Charge Recycled-AFE having an Chopper-Stabilized Capacitive-Coupled IA including bias sampling capacitors that store bias values associated with the first and second channels to enable swapping between the channel, and a DC servo loop (DSL) having a reduced setting time based on a reduction in a resistance of the pseudo-PMOS in response to engaging a system reset. The classification processor includes a Frequency-Time Division Multiplexing (FTDM) Feature Extraction (FE) engine and a Dual-Detector Architecture (D2A) classification processor. The FTDM-FE includes a plurality of FIFOs configured to store, in parallel, the digitized data corresponding to the channels, a plurality of BPF banks storing BPF coefficients, and a single BPF to calculate outputs of one specific bank of the BFP banks for all of the channels. The D2A processor receives the output from the FTDM-FE and estimates a beginning and end of a seizure using two LSVMs optimized for only sensitivity and specificity, respectively.
