Abstract
An integrated constant time delay circuit utilized in continuous-time (CT) analog-to-digital converters (ADCs) can be implemented with an RC lattice structure to provide, e.g., a passive all-pass lattice filter. Additional poles created by decoupling capacitors can be used to provide a low-pass filtering effect in some embodiments. A Resistor-Capacitor 'RC' lattice structure can be an alternative to a constant-resistance Inductor-Capacitor 'LC' lattice implementation. ADC architectures benefit from the RC implementation, due to its ease of impedance scaling and smaller area.
