“…The third‐order intermodulation cancelation technique introduced in works is applied to the dual‐linearity‐mode mixer when M SC1 ‐M SC4 are OFF and M SD1 ‐M SD4 are ON (Figure C). Here, M 1 is forced to operate in a weak inversion region by a current mirror formed by M 2 and M 3 that operate in a strong inversion region, thereby resulting in a LO‐DBAM mixer.…”

Summary This work illustrates a flexible and convenient method to build a multimode narrowband receiver RF front‐end by means of controlled switches, switched capacitors, and switched inductors. The front‐end comprises a dual‐gain‐mode narrowband low‐noise amplifier (LNA) and a dual‐linearity‐mode mixer. A four‐mode receiver RF front‐end constructed with the dual‐gain‐mode LNA and the dual‐linearity‐mode mixer operating in frequency band range from 1800 to 2050 MHz was demonstrated with an IBM 90‐nm CMOS process. The front‐end achieves a 1/1.6 dB noise figure, 30/20 dB power gain, and 16/−10 dBm third‐order input intercept point while draws a 5.9/3.6 mA current from a 1.8‐V supply voltage at the low noise mode and high linearity mode, respectively. The proposed technique can be employed to build an intelligent mobile system.

“…For low frequency band (0.1-0.75GHz), 8-phase LOs are generated from 4f LO differential signals with two cascaded divided-by-2 circuits [4], which will introduce phase ambiguity. This issue is critical since 8-phase LOs may operate in either one of the two stable modes (Case-1 and Case-2), as shown in Fig.…”

“…Traditional 8-phase LOs for HR are generated from 4f LO (f LO is operation frequency of receiver) differential signals [4], which increases the design complexity and power consumption of the frequency synthesizer significantly. In this work, a hybrid 8-phase LO generation technique is proposed to reduce the highest operation frequency of the frequency synthesizer by half.…”

A 0.1-1.5GHz harmonic rejection (HR) receiver front-end is presented. A flexible HR mixer is proposed to correct phase ambiguity, and a vector gain calibration is used to eliminate the gain/phase mismatch and improve the HR ratio. With the proposed hybrid 8 phase local oscillating (LO) generator, the highest carrier frequency from the frequency synthesizer is only twice of the desired LO frequency. The HR receiver has been implemented in 65nm CMOS. With 1.8mm 2 core chip area and 5.4-24.5mA current consumption from a 1.2V power supply, the receiver achieves 85dB conversion gain, 4.3dB NF, +13dBm/+14dBm IB/OB-IIP3, >54/56 dB HR3/HR5 with 30-40dB improvement by calibration, and 2.3% EVM with 32QAM modulation signal.

Hard-switched mixers have attractive linearity and noise properties, but are plagued by spurious responses due to the harmonic content of square-wave local oscillator (LO) signals. Harmonic rejection mixers (HRMs) reject (some of) these responses and can be constructed combining polyphase mixing and amplitude weighting. This paper presents a generalized model for the analysis of the harmonic rejection (HR) of such HRMs, based on circular convolution. We show that the effective LO signal can be modeled as a periodic Dirac impulse filtered by a time-discrete filter. For a multi-stage HR system, this filter consists of multiple stages as well, and the coefficients of each stage can be found simply by inspection. The total HR is shown to be the sum (in dB) of the rejection of the individual filtering stages, highly simplifying analysis and design of HRMs.
