Techniques for Pixel Level Analog to Digital Conversion

Two techniques for performing pixel level analog to digital conversion (ADC) are reviewed. The first is an oversampling technique which uses a one bit first order Ez modulator for each 2 x 2 block of pixels to directly convert photocharge to bits. Each modulator is implemented using 17 transistors. The second technique is a Nyquist rate multi—channel--bit—serial (MCBS) ADC. The technique uses s...

Digital Techniques for Improved AX Data Conversion

Two digital techniques are described in this tutorial, both aimed at improving the accuracy of delta-sigma data converters. The first one corrects adaptively for mismatch errors in a MASH ADC, while the other acquires and then corrects for the nonlinearity of the intemal multibit DAC used in the ADC.

Analog to Digital Conversion

1 ADC TYPES Analog-to-Digital Converters (ADCs) transform an analog voltage to a binary number (a series of 1’s and 0’s), and then eventually to a digital number (base 10) for reading on a meter, monitor, or chart. The number of binary digits (bits) that represents the digital number determines the ADC resolution. However, the digital number is only an approximation of the true value of the ana...
