ABSTRACT:
According to one general aspect, an apparatus may include a terminal configured to receive an analog input signal. In various embodiments, the apparatus may also include a multistage amplifier configured to amplify the analog input signal by an amount of gain. In some embodiments, the apparatus may include a distributed threshold adjuster interspersed between the stages of the multistage amplifier configured to adjust the DC voltage of the analog input signal to facilitate a decision by an analog-to-digital converter (ADC). In one embodiment, the apparatus may include the ADC configured to convert the amplified analog input signal to a digital output signal.
