NON-LINEARITY CORRECTION THAT IS INDEPENDENT OF INPUT COMMON MODE, TEMPERATURE VARIATION, AND PROCESS VARIATION |
摘要 |
In pipeline analog-to-digital converters (ADCs) the third harmonic can degrade the performance of the ADC, and conventional circuits that attempt to cancel this third harmonic are oftentimes sensitive to process variation, temperature variation, and common mode variations. Here a correction circuit is provided that includes a compensator that adjusts control voltages for MOS capacitors to generally ensures that the difference between the gate-source voltages and threshold voltages of MOS capacitors is generally maintained across variations of process, temperature, and common mode.
