Peak detectors (peak-detect-and-hold circuits, PDHs) are a key element in nuclear electronics signal processing and have been incorporated as a fully integrated block in several front-end readout chips. In CMOS designs, the PDH uses an MOS current source as the rectifying element inside the feedback loop of a high-gain amplifier. However, the nonidealities in the amplifier and feedback elements...

This paper reports a lateral CMOS-MEMS accelerometer with a measured noise floor of 1mG/ and a dynamic range larger than 13G. The accelerometer is fully compatible with conventional CMOS processes enabling the integration of most of the conditioning circuits. It is fabricated in a three metal layer 0.5μm CMOS process followed by a two-step dry etch release. An improved curl matching technique i...

A novel low-voltage two-stage operational amplifier employing resistive biasing is presented. This amplifier implements neutralization and correction common mode stability in second stage while employs capacitive dc level shifter and coupling between two stages. The structure reduces the power consumption and increases output voltage swing. The compensation is performed by simple miller method....

Within the Clemps project (Closed-Loop Embedded MEMS-based Precision Stage) we investigate the fabrication of MEMS-based stages with up to three degrees of freedom. These stages are to be used in, for example, transmission electron microscopy applications and probe based data storage. The project is a close cooperation with the MA group of IMPACT. The desired stages are characterized by a numbe...

This paper presents a high speed and low energy transceiver for 10mm long minimum width on-chip global interconnects. To improve the link bandwidth, the transmitter employs a capacitive-resistive pre-emphasis technique and the receiver employs the AC-coupled Resistive Feedback Inverter (RFI) de-emphasis technique. Exploiting two emphasis techniques, the proposed interconnect achieves 1.26GHz ba...

This paper describes Squeezy: a low-cost, tangible input device that adds multi-dimensional input to capacitive multi-touch tablet devices. Force input is implemented through force sensing resistors mounted on a rubber ball, which also provides passive haptic feedback. A microcontroller samples and transmits the measured pressure information. Conductive fabric attached to the finger contact are...

We consider the technical possibility of an adaptive contact lens and an adaptive eye lens implant based on the modal liquid crystal wavefront corrector, aimed to correct the accommodation loss and higher-order aberrations of the human eye. Our first demonstrator with 5 mm optical aperture is capable of changing the focusing power in the range of 0 to +3 diopters and can be controlled via a wir...

In this work, the authors introduce a new full-analog front-end for differential capacitance sensors which provides a DC output voltage, directly proportional to the measurand variations. The readout circuit architecture is based on a De Sauty bridge as core of the capacitive sensing whereas the feedback circuitry performs the bridge autobalancing operation by means of changes in a multiplier o...
