A novel photonic analog-to-digital conversion scheme using Mach-Zehnder modulators (MZMs) with identical half-wave voltages and multiple comparators with improved bit resolution is proposed and demonstrated. Compared with the scheme using MZMs with geometrically scaled half-wave voltages, the propos
