RC lattice delay
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.
Static compensation of an active clock edge shift for a duty cycle correction circuit
Duty cycle correction devices for static compensation of an active clock edge shift. A duty cycle correction circuit in the duty cycle correction device corrects a clock input signal, according to a first control signal. A programmable delay circuit or a modified duty cycle correction circuit in the duty cycle correction device compensates a shift of an active clock edge in a clock output signal of the duty cycle correction circuit, according to a second control signal. A mapping circuit in the duty cycle correction device generates the second control signal by mapping a digital value of the first control signal and a digital value of the second control signal.
