ANALOG BUFFER UNIT AND OPERATION METHOD THEREFOR, AND ANALOG BUFFER

WIPO Patent Application WO/2024/050955

A1

An analog buffer unit and an operation method therefor, and an analog buffer. The analog buffer unit comprises an input circuit, a storage circuit, a windowing circuit, and an output circuit. The input circuit is configured to be switched on or off according to an input control signal so as to start to receive or stop receiving an input signal; the storage circuit is configured to receive the input signal from the input circuit and to buffer a sampled input signal in the storage circuit in the form of analog data; the windowing circuit is configured to perform, according to a windowing control signal, window function coefficient adjustable windowing on the analog data buffered in the storage circuit; and the output circuit is configured to be switched on or off according to an output control signal so as to output the windowed analog data in the analog buffer unit. According to the analog buffer unit, by truncating an input signal having an infinite length by means of the storage circuit, and performing window function coefficient adjustable windowing on the truncated input signal by means of the windowing circuit, spectral leakage of the truncated input signal can be reduced on an analog domain.
