Abstract
Recent research in true time delay based phased array receivers have allowed for applications
with large fractional bandwidths and time delays to become realizable. The spatial processing of
the multiple such received signals in the phased-array can be done in various domains such as
charge-domain or time-domain. This work presents design considerations of the main signal path
in both contexts, highlighting the benefits and drawbacks for both. The signal path in this design
is critical to achieving desired beamforming and relative channel delay. The method of signal
summation was done through a novel non-uniform sampling technique developed at Washington
State University. This work proposes two architectures, one in the time domain and the other in
the charge domain for bandwidths of 500MHz to 800MHz that stem from the current state-of-theart in recent literature. By comparing the performance of each architecture in their respective
domains, a design methodology can be established for a given set of specifications. All circuits
were designed and fabricated in the TSMC 65nm CMOS process.
