meters, appliances, smoke alarms to ground fault detectors require a non-isolated DC supply that is powered directly from the AC mains. These applications typically require the ability to handle up to 305VAC,rms at the i

Many sensing applications require a high-resolution frequency measurement. These applications include measurement of pressure, acceleration and eddycurrent sensing. In these applications the sensor is part of an oscillat

1.1 Introduction Scaling of CMOS, the technology that has driven our industry for 45 years and prompted unprecedented innovations in device, circuit, and manufacturing, is coming to an end. There is no unanimous agreemen

Wireless nodes in Internet-of-Everything (IoE) applications achieve low power consumption by operating the radio at very low duty cycles. The wireless node spends most of its time in sleep, waking only occasionally to tr

Low-offset and low-noise operational amplifiers (OpAmps) are essential for precision measurement systems. Applications such as precision weigh scales, sensor front-ends, bridge transducers, interfaces for thermocouple se

reductions in power, cost and size of wireless sensors. Wireless nodes reduce average power by using intermittent data transmission, which is synchronized by a continuously operating sleep timer in each node. In some app

In wireless networks with a low duty cycle, the radio is operational for only a small percentage of the time. A sleep timer is used to synchronize the data transmission and reception. The total system power is then limit

fine-resolution quantization to reduce the out-of-band noise (OBN), reduce jitter sensitivity, and simplify analog filtering. Recent techniques achieve this goal by using a mix of DAC elements with different weights, e.g

A 36V JFET-input bipolar operational amplifier is presented with a maximum offset drift of 1µV/°C over a temperature range of –40 to 125°C, which represents a 3x improvement on the state-of-the-art. This is achieved with

Integrating audio and power management into a system-on-chip (SoC) is of interest due to reduced board area and cost. Integrated Class-D audio drivers need to drive high voltages to deliver high power across small loads;

The RX signal path in wireless base transceiver stations (BTS) drives the continued development of high-resolution high-speed ADCs. Such ADCs enable BTSs with software-defined and/or multi-carrier capability, such as mul

Due to their rail-to-rail switching nature, Class-D audio amplifiers are prone to generating electromagnetic interference (EMI) that is in excess of what is acceptable in many systems. Such systems typically require devi
