Abstract
A method and apparatus precondition an analog signal and convert the preconditioned signal into a digital representation. The method includes preconditioning the analog signal, generating a quantity N of reference signals, comparing an amplitude of the preconditioned signal to an amplitude of the reference signals to determine whether the preconditioned signal amplitude is greater than, less than or equal to reference signal amplitudes, and producing a timestamp at a time that the preconditioned signal and reference signal amplitudes are equal. The apparatus includes a preconditioner, a reference signal generator and a quantity N of comparators. A comparator of the quantity N of comparators receives the preconditioned signal from the preconditioner, separately receives a reference signal, and produces a digital signal. The preconditioned signal or the analog signal may be reconstructed from the digital representation.
