Time-Interleaved SAR ADC with Background Timing-Skew Calibration for UWB Wireless Communication in IoT Systems

Abstract: Ultra-wideband (UWB) wireless communication is prospering as a powerful partner of the Internet-of-things (IoT). Due to the ongoing development of UWB wireless communications, the demand for high-speed and medium resolution analog-to-digital converters (ADCs) continues to grow. The successive approximation register (SAR) ADCs are the most powerful candidate to meet these demands, attracting both industries and academia. In particular, recent time-interleaved SAR ADCs show that multi-giga sample per second (GS/… Show more

“…As the name implies, it attempts to detect, identify, and isolate intrusion attempts or unauthorized use of computers [11]. With the continuous discovery of system vulnerabilities and attacks, the status of the intrusion detection system in the whole security system continues to improve, and its role is becoming greater and greater [12]. Figure 1 shows the research on the design method of intrusion detection system for the wireless network.…”

“…The temperature estimation function of this type of time domain CMOS temperature sensor is defined as the ratio of two different temperature dependent delay times. The typical structure of this type of temperature sensor, which was proposed by P. Chen et al in 2010 [38], includes two delay lines, of which delay times vary in a different way from each other with respect to temperature, and a successive approximation register (SAR) control logic [76][77][78][79][80][81][82][83][84][85][86][87] implemented as an FSM. For example, if one of these delay lines is composed of the general inverter type delay cells of Figure 5b, then the other is composed of the delay cells shown in Figure 6b which are less sensitive to temperature [33,38].…”

“…Ultra-low power consumption is required in these systems for signal sensing and processing to provide a long battery life. An analog-to-digital converter (ADC) is a key component in the processing of sensor output [ 1 , 2 , 3 ] and wireless communication [ 4 , 5 ]. Among various ADCs, successive approximation register (SAR) ADC is suitable for achieving high energy efficiency with low power consumption [ 6 ].…”
