A Duffing oscillator with weighted sample readout estimates phase, amplitude, and frequency while cutting DSP power use and chip area.
Signal-region detection switches the differential amplifier and ADC to standby in inactive states, cutting neural network power use.
ALU-based signal shifting and scaling let memristor crossbar arrays handle negative values and wide dynamic ranges with accurate output.
Nearest-neighbor charge-packet cells remove global clocking and cut interconnect bottlenecks for scalable, lower-power logic.
Continuous-state analog cells use local message passing to cut interconnect bottlenecks and power in distributed signal processing.
Airborne signal detection determines touch location and hold events using ultrasonic waves, resolving integration complexity in varying device geometries.
