  • CLASS-D AMPLIFIER
    Publication number: 20130147552
    Abstract: A class-D amplifier includes a quantized amplifier, having no quantization error feedback circuit, coupled to receive a digital input signal, according to which an output signal is generated to be switched between power rails. The digital input signal is pre-compensated to correct an error. A low-pass filter is configured to operate on the output signal to generate a filtered output signal.

  • EVENT-BASED BIO-SIGNAL CAPTURING SYSTEM
    Publication number: 20130150698
    Abstract: An event-based bio-signal capturing system is disclosed. At least one bio-signal capturing device captures a bio-signal measured from biological beings; and at least one event capturing device captures an event and generates a corresponding event marker. A data recording device acquires the bio-signal and the event marker, wherein the bio-signal and the event marker are acquired with corresponding time reference for subsequent event-based data analysis.
