In this paper, an optimal approach to design wideband tapped-delay line (TDL) array antenna is proposed. This approach lets us control the array angular and frequency response over a wide frequency band. To this end, some design restrictions are defined and a multi-objective optimization problem is constructed by putting the individual restrictions together. The optimal weights of the TDL proce...

uniform linear array (ula)-based tapped-delay line (tdl) structure has good performance metrics when the signal sources are located at the middle angles. it offers poor performance when the signal sources are close to the array endfire. in this paper, a new approach is proposed which offers higher performance and desired beamforming on tdl structure when the wideband uncorrelated radio sources ...

This paper proposes a digital delay locked loop (DLL) with monotonic line (DL). DLL adopts the calibration mode to reduce non-monotonic effects for coarse-tuning (CTDL) and fine-tuning (FTDL). The detects time of unit, timing resolution CTDL, adjust range FTDL. Thus, can limit overlap between CTDL proposed was implemented using 0.18-μm CMOS process, RMS peak-to-peak jitters were 0.21% 1.72%, re...
