Title: Low-Power Multi-Band Injection-Locked Wireless Receiver

ABSTRACT

The demand for low-power, high-performance wireless receivers has dramatically increased with the emerging deployment of wireless sensor networks (WSNs). Among the demodulation schemes, non-coherent receivers consume less power in comparison with its counterpart, e.g. the coherent receiver, attributed to its simple architecture and fewer components.

The injection-locking based envelope detection design, consisting of a low-noise amplifier (LNA), injection-locked oscillator, and an envelope detector, has drawn a lot more attention in recent years for low-power non-coherent demodulation. However, the utilization of the injection-locked oscillator, providing flexibility and high performance, remains quite challenging. This thesis describes both the circuit level and mathematical model of injection-locking, allowing for the implementation of a CMOS receiver offering low-power, high performance and the ability to support multiple radio frequency bands.

By leveraging both fundamental and superharmonic injection-locking, the receiver is capable of operating at five frequency bands, e.g., 433 MHz, 863 MHz, 915 MHz, 950 MHz, and 2.4 GHz, used for WSN applications. One of the challenges of making use of superharmonic injection-locking is the narrow lock range that is insufficient for the oscillator to implement frequency-to-amplitude conversion under the locked-in status while maintaining low-power performance. A mathematical model developed in this work reveals the relationship between the lock range of superharmonic injection-locking and the third-order coefficient of the nonlinearity.

An examination of the injection transistor operating in the weak and strong inversion region leads to the discovery of an optimal biasing point in the subthreshold region where the maximum lock range can be attained. Moreover, a further investigation of the dependence of the third-order coefficient of the nonlinearity and the lock range is demonstrated. As a consequence, a technique to additionally extend the lock range via body biasing and p-well injection using a triple-well NFET device is presented.

The receiver was designed in GF 130 nm CMOS technology with a 0.7 V supply voltage. Based on the simulation results, the design achieves a data rate of 5 Mbps for four of the frequency bands and 4 Mbps for the 433 MHz band for both FSK and OOK signals. With two modes of operation, the receiver consumes 770 mW and 685 mW of static power, while achieving a sensitivity of -85 dBm and -75 dBm. The FOM for each mode is 155pJ/b and 137 pJ/b. The linearity properties, e.g., 1-dB compression point (P1dB), third-order intercept (IIP3) of LNAs, suffers significantly in ultra-low-power (ULP) applications attributed to the biasing condition of the main transistor.

To alleviate this issue, there is typically a trade-off with voltage gain and power performance, degrading the overall design. Based on the investigation of the relationship of the biasing point and the nonlinearity of the transistor, a complementary common-source (CS) LNA was designed in GF 130 CMOS process for optimal voltage gain, power consumption, and linearity. By using the symmetrical properties of the NFET/PFET pair, the linearity of the LNA is enhanced. As a result, the simulated voltage gain, IIP3, P1dB, and NF are 15.7 dB, -6.5 dBm, -17.5 dBm and 5.7 dB respectively.

The total power consumption is 35 uW from a 0.7 V supply voltage. The evaluated performance of the design using a classical figure of merit (FOM), achieves the highest known value by a significant margin in comparison with state-of-the-artwork.


Participate in the English Language Centre's Homestay Program!

The English Language Centre is calling on Lakehead University's community to welcome Mexican students into their homes over the fall semester.

Each year the English Language Centre runs a Homestay program that gives international students the opportunity to live with a family in Thunder Bay while taking classes at the University. Many of our students choose this program in order to have a full English immersion experience, where they not only improve their language skills but also learn about Canadian culture.

This year we are looking for individuals from the Lakehead University community to welcome students into their homes for the fall semester from September 1 to December 15!

If you would like to participate in the Homestay program, you will receive a stipend to off-set the costs of hosting a student in your house.

If you are interested in participating in this program, please visit this page to complete the sign-up form on or before August 11.

If you require more information, please contact the English Language Centre by e-mail at international.english@lakeheadu.ca or by phone at (807) 346-7888.
