Analysis of Active Pixel Sensor Readout Circuit
This brief provides a detailed analysis of active pixel sensor, pixel and column circuit. Surprisingly, we find that shorter readout times can be achieved by reducing the bias current and hence reducing energy consumption. We investigate the effect of nonidealities on the readout operation. We find that when the follower transistor channel-length modulation is taken into consideration, delay is...

متن کاملDesign of Cmos Readout Frontend Circuit for Mems Capacitive Microphones
This paper deals with a frontend part of the readout circuit developed as an integrated circuit that after bonding together with a MEMS capacitive microphone (MCM) chip will be used in a noise dosimeter applicable in very noisy and harsh environment, e.g. mine. Therefore, the main attention has been paid to the high dynamic range, low offset and low noise of the developed readout interface as w...
متن کاملImproved Circuits with Capacitive Feedback for Readout Resistive Sensor Arrays
One of the most suitable ways of distributing a resistive sensor array for reading is an array with M rows and N columns. This allows reduced wiring and a certain degree of parallelism in the implementation, although it also introduces crosstalk effects. Several types of circuits can carry out the analogue-digital conversion of this type of sensors. This article focuses on the use of operationa...
متن کاملA Digital Readout Technique for Capacitive Sensor Applications
The difference between two capacitors is measured digitally using a charge redistribution techrdque incorporating a comparator, MOS switches, a successive approximation register (SAR), and a dlgital-to-anaIog converter (DAC). The technique is insensitive to comparator offset and parasitic capacitance, and the effect of MOS switch charge injection is measured and canceled. Extensive measurements...
