Abstract

Technology scaling greatly benefits discrete-time and N-path filters, making them perfect for Software-Defined Radio and wireless Standards designs. Both strategies enable wide-band and narrowband solutions, high selectivity and easy programmability with low power and high linearity. This paper presents a review of discrete-time and N-path based receivers. Their architecture similarities are examined, focusing on discrete-time receiver building blocks whose features and advances are detailed. An extensive literature review of the State-of-the-Art on these strategies is conducted.
