Design of a high speed capacitive digital-to-analog converter (SC DAC) is presented for 65 nm CMOS technology. SC pipeline architecture is used followed by an output driver. For GHz frequency operation with output voltage swing suitable for wireless applications (300 mVpp) the DAC performance is shown to be limited by the clock feed-through and settling effects in the SC array rather than by th...

A skip and fill algorithm is developed to digitally self-calibrate pipelined analog-to-digital converters (ADC’s) in real time. The proposed digital calibration technique is applicable to capacitor-ratioed multiplying digital-to-analog converters (MDAC’s) commonly used in multi-step or pipelined ADC’s. This background calibration process can replace, in effect, a trimming procedure usually done...

We have performed self-consistent, three-dimensional (3-D), time-domain calculations for a bounded-wave electromagnetic pulse simulator. The simulator consists of a constantimpedance transverse electromagnetic structure driven by a charged capacitor, discharging through a fast closing switch. These simulations yield the detailed 3-D electromagnetic field structure in the vicinity of the simulat...

This paper proposes a pipeline analog-to-digital converter (ADC) with non-binary encoding technique based on β-expansion. By using multiply-by-β switched-capacitor (SC) multiplying digital-to-analog converter (MDAC) circuit, our proposed ADC is composed by radix-β (1 < β < 2) 1 bit pipeline stages instead of using the conventional radix-2 1.5 bit/1 bit pipeline stages to realize non-binary anal...

We proposed the hydrogenated amorphous silicon thin-film transistor (a-Si:H TFT) pixel electrode circuit with current-scaling function which is suitable for active-matrix organic light-emitting displays (AM-OLEDs). In contrast to the conventional current-mirror circuit, this circuit with the cascaded storage capacitors can provide a high data-to-organic light-emitting device (OLED) current rati...

This paper presents a 64×64 pixel micro-bolometer based temporal contrast IR sensor. The pixels of the sensor independently and asynchronously respond to changes in thermal IR radiation and communicate respective events via arbitrated AER. A 46dB-gain, small-area, ultra low-power, low-mismatch differencing switched-capacitor amplifier has been designed for reading out the bolometer front-end. T...

We experimentally demonstrate an all-silicon optical transmission controller based on a semiconductor-oxide-semiconductor capacitor embedded in a slot photonic-crystal waveguide. We incorporate a multimode interference-based structure to reduce the coupling loss induced by the waveguide mode mismatch. We perform a detailed DC characterization of the electro-optic device including the DC modulat...

background: a potential specific problem of patellar tendon graft in acl reconstruction is the possibility of graft-tunnel mismatch which could be more problematic with anatomic acl reconstruction where the femoral tunnel is placed low on the lateral wall of the lateral femoral condyle. the occasional occurrence of this mismatch raises the question that whether a correlation exists between pati...
