A new current-mode bandgap reference circuit (BGR) which is capable of generating sub-1-V output voltage is presented. It has not only the lowest theoretical minimum current consumption among published current-mode BGRs, but also additional advantages of an inherent curvature-compensation function and not requiring NPN BJTs. The curvature-compensation is achieved by utilizing the exponential behavior of sub-threshold CMOS transistors to compensate the BJT base-emitter voltage high-order temperature dependence. By taking advantages of the continuing development of CMOS technology, sub-µW power consumption is achieved with a reasonable core area. Related design considerations and challenges are discussed and analyzed. The proposed BGR is realized in a TSMC 90 nm process. Measurement results shows a temperature coefficient without trimming as low as 10.1 ppm/°C over a temperature range of 70°C because of the proposed curvature-compensation technique. The average value is 32.6 ppm/°C which could be improved by trimming resistor ratios. The average power consumption at room temperature is 576 nW, with a core area of only 0.028 mm².

A low-power on-off-keying impulse-radio (IR) ultra-wideband (UWB) pulse generator (PG) intended for wireless-powered IR-UWB radio applications is presented. The proposed PG has high flexibility, the center frequency, output power and pulse-width (PW) are controllable depending on channel conditions and data rates. Qualitative frequency-domain and transient analyses are presented. A new figure-of-merit (FoM) is proposed such that a more precise comparison between different PGs can be made. The PG is successfully implemented in a TSMC 90 nm CMOS process, measurements show the energy consumption and FoM to be 2.8–7.5 pJ/pulse and 1.6–2.6% respectively. The output swing and PW are 277–329 mVp-p and 509–1088 ps respectively. The core area is 0.092 mm².

An impulse radio ultrawideband (IR-UWB) transmitter (TX) intended for long-range passive radio-frequency (RF) identification tags is presented. It is wirelessly powered by an ultrahigh-frequency (UHF) signal. A 128-bit pseudonoise code is transmitted when enough energy is harvested. A new on-off-keying multicycle energy-efficient IR-UWB pulse generator (PG) is proposed, and a co-design with power management circuits is introduced to improve the system supply noise performance. A novel injection-locking divider co-designed with an RF voltage rectifier is proposed to eliminate the injection input resistive load that exists in some designs; otherwise, the input sensitivity would be degraded. A proof-of-concept prototype is fabricated in a TSMC 90-nm CMOS process. Measurements show the TX input sensitivity to be approximately -17.5 dBm with a 900-MHz UHF input. The measured PG output swing is 195 mVp-p with a -10 dB bandwidth of approximately 3.4 GHz.

In this thesis, we present a neuromorphic approach to the sound source localization problem, based on the Jeffress model of sound source localization. The proposed system uses binary neural spike coding and asynchronous axonal delay lines to efficiently compute the cross-correlation in the time domain and determine the interaural time delay (ITD) between binaural input signals. While more research is needed, the proposed approach potentially offers significant improvements over current hardware implementations, with regards to power consumption and response time. In the test cases simulated, the system estimates the ITD to within 10us, with an average power consumption of 350nW. Simulations also showed a sub-millisecond reaction time to changes in the ITD. However, the proposed system is highly dependent on accurate component matching for proper functioning, and we find that additional compensation techniques would be required for a fabricated chip.
