This paper presents a reconfigurable multi-sensor interface and its readout integrated circuit (ROIC) for display-based multi-sensor systems, which builds up multi-sensor functions by utilizing touch screen panels. In addition to inherent touch detection, physiological and environmental sensor interfaces are incorporated. The reconfigurable feature is effectively implemented by proposing two ba...

We propose methods for the preparation and entanglement detection of multi-qubit Greenberger–Horne–Zeilinger (GHZ) states in circuit quantum electrodynamics. Using quantum trajectory simulations appropriate for the situation of a weak continuous measurement, we show that the joint dispersive readout of several qubits can be utilized for the probabilistic production of high-fidelity GHZ states. ...

This paper presents a Universal Micro-Sensor Interface (UMSI) circuit designed for low-power microsystems that support multiple sensors and actuators. The interface chip contains all necessary reference, readout, control, and communication circuitry to interface a range of capacitive, resistive, voltage, or digital output devices to system control hardware. For online configuration of many para...

This paper presents a resolution-reconfigurable wide-range resistive sensor readout interface for wireless multi-gas monitoring applications that displays results on a smartphone. Three types of sensing resolutions were selected to minimize processing power consumption, and a dual-mode front-end structure was proposed to support the detection of a variety of hazardous gases with wide range of c...

A new hybrid optical detector is described that has many of the attributes desired for the next generation adaptive optics (AO) wavefront sensors. The detector consists of a proximity focused MCP read out by multipixel application specific integrated circuit (ASIC) chips developed at CERN (“Medipix2”) with individual pixels that amplify, discriminate and count input events. The detector has 256...

This article describes the most recent generation of full-custom analog integrated circuit that is intended for low-power, high-speed sampling of Radio-Frequency (RF) transients in excess of the Nyquist minimum. A direct descendant of the Self-Triggered Recorder for Analog Waveforms (STRAW) architecture, and earlier variants of the LABRADOR (Large Analog Bandwidth Recorder and Digitizer with Or...

Abstract A real-time 3-D image sensor with VGA (640 × 480) resolution based on triangulation is presented. The sensor employs an adaptive thresholding circuit and column-parallel time-domain approximate ADCs to realize high-speed readout for real-time range finding. Sub-pixel position calculation based on intensity profile by the readout scheme achieves high-accuracy range finding. A column-par...

Nanoelectronic molecular and magnetic tunnel junction (MTJ) MRAM crossbar memory systems have the potential to present significant area advantages (4 to 6F(2)) compared to CMOS-based systems. The scalability of these conductivity-switched RAM arrays is examined by establishing criteria for correct functionality based on the readout margin. Using a combined circuit theoretical modelling and simu...
