  5GHz CMOS all-pass filter-based true time delay cell 

  Aghazadeh Dafsari, Seyed Rasoul; Martínez García, Herminio; Saberkari, Alireza (Multidisciplinary Digital Publishing Institute (MDPI), 2020)
  Part of book or chapter of book
  Open Access

  Analog CMOS time-delay cells realized by passive components, e.g., lumped LC delay lines, are inefficient in terms of area for multi-GHz frequencies. All-pass filters considered as active circuits can, therefore, be the ...
