Channel selection at the input of RF receivers can considerably relax linearity requirements, leading to low-power, compact implementations. A GSM/WCDMA/802.11b/g receiver incorporates a Miller bandpass filter and its variants to achieve a channel bandwidth from 350 kHz to 20 MHz and a noise figure of 2.9 dB while consuming 20 mW. Fabricated in 65 nm CMOS(More)
BACKGROUND AND OBJECTIVES There is little information about the relationship between the Doppler flow of the ophthalmic artery (OA) and carotid and coronary atherosclerosis. The aim of the investigation was to assess the clinical usefulness of the Doppler flow of the OA to estimate the severity of carotid and coronary atherosclerosis. SUBJECTS AND METHODS(More)
Miller bandpass filters combine the properties of Npath circuits with the Miller effect to achieve a narrow bandwidth and high out-of-channel rejection. This paper investigates the second-order intermodulation behavior of such filters in the context of direct-conversion receivers. It is shown that the second intercept point rises by an amount equal to the(More)
