Tunable True Time Delay Element:

• Introduces widely tunable delays over wideband signals, crucial for applications like beamforming and continuous-time equalizers.

All-Pass Filter Architecture:

• Utilizes a weighted sum of input voltages and one-port networks to achieve tunable delays.

Variable LC Ladder Circuits:

• Allows for precise control over delay order by adjusting the number of stages, enhancing flexibility in delay adjustment.

Lossless and Lossy Transmission Lines:

• Offers options for adjustable delay by varying length, with lossy lines providing additional control over delay characteristics.

Integrated Circuit Implementation:

• Incorporates operational transconductance amplifiers (OTAs) and digital logic for order selection and capacitance programming, facilitating integration into signal processing systems.
