A 65 nm CMOS Wideband Radio Receiver with ΔΣ-Based A/D-Converting Channel-Select Filters
(2016) In IEEE Journal of Solid-State Circuits 51(7). p.1566-1578- Abstract
This paper presents a wideband quadrature radio receiver employing ΔΣ-based A/D-converting channel-select filters (ADCSFs). The output of the quadrature passive mixer is directly connected to the input of the ADCSFs, where a first-order ΔΣ modulator is incorporated into a fourth-order Butterworth channel-select filter (CSF) to provide sufficient dynamic range for a cellular system. A design methodology for the ADCSF is derived, where the transfer function of the CSF is preserved. The 65 nm CMOS receiver has a frequency range of 0.6-3.0 GHz and can be programmed to support the 2xLTE20, LTE20, and LTE10 bandwidths. The receiver noise figure varies from 2.3 to 3.9 dB, with a current consumption in 2xLTE20 mode between 33 mA at 0.6 GHz and... (More)

The 65 nm CMOS receiver has a frequency range of 0.6-3.0 GHz and can be programmed to support the 2xLTE20, LTE20, and LTE10 bandwidths. The receiver noise figure varies from 2.3 to 3.9 dB, with a current consumption in 2xLTE20 mode between 33 mA at 0.6 GHz and 44 mA at 3.0 GHz from a 1.2 V supply, including 10-21 mA for LO phase generation and distribution. The SNDR is 47-51 dB at an LO frequency of 1.8 GHz.
