TLDR
A model describing the time constant of a transmission-line integrator is presented, and the integrators with equal-length transmission lines with good agreement with theoretical values are implemented.Abstract:
A model describing the time constant of a transmission-line integrator is presented. By representing the formulations of integrators in the discrete-time (or Z) domain, we implement the integrators with equal-length transmission lines. Three integrators with different time constants and frequency bands are built and tested. The experimental results are in good agreement with theoretical values.read more
