Abstract
An input apparatus and an electronic device applying the input apparatus. The input apparatus includes: at least one sensor, configured to detect an inputting operation, and output a first signal based on the inputting operation; at least one amplifying circuit, configured to amplify a difference between the first signal and a referential signal, to output a second signal, where each of the at least one amplifying circuit comprises a plurality of stages, each of the plurality stages comprises an amplifier, and a high-pass filter is connected between last two stages of the plurality of stages; and an analog-digital converter, configured to convert the second signal into a digital signal characterizing a state of the inputting operation, where the ADC comprises at least one comparator. Users can give instructions through novel inputting operations, and performances of the electronic device are greatly improved.
