Project Code :TVMABE400

Objective

Design a Gated Delay-Line Based Counter • Develop a novel up-down counter architecture that uses a gated delay line to generate timing for count increments/decrements. • Enable fine control over counting by gating the delay line (i.e., enabling or disabling pulses) so that the counter only advances when mixed-signal conditions require it.

Abstract

Gated delay line up-down counters play a vital role in mixed-signal processing systems by enabling accurate time-to-digital and phase-related measurements. This work presents a gated delay line based up-down counter architecture that improves counting accuracy while reducing power consumption. The proposed design employs controlled delay elements and gating mechanisms to regulate signal propagation and counting direction. By integrating digital counter logic with delay-based signal processing, the architecture achieves efficient operation under varying input conditions. The gated approach minimizes unnecessary switching activity, enhancing energy efficiency and robustness. The proposed counter is well suited for mixed-signal applications such as time-based signal processing, frequency measurement, and data conversion systems.
