Due to the absence of internal nodes, inverter-based Gm-C filters [1,2] allow achieving bandwidths beyond what is possible with opamp-RC techniques. The inverter's class-AB behavior, together with the high transconductance per quiescent current, results in a high dynamic range per power when optimally biased [3]. The major disadvantage of traditional(More)
—This paper describes a combination of a Weaver mixer and an N-path filter for a superheterodyne receiver with a reconfigurable frequency plan. It uses an N-path topology driven with two different frequencies, effectively realizing a frequency shift together with band-pass filtering. To reduce transfers via harmonics other than the fundamental, a harmonic(More)
