Assignee: TEXAS INSTRUMENTS INCORPORATED
Field: Basic communication processes (Electrical engineering)
Classification: CPC H | IPC H

Claim 20:
21. The method of claim 19 further comprising:
activating a first preamplifier, the ADC includes the first preamplifier and a second preamplifier, the first and second preamplifiers have successive threshold voltages;
processing M+L input codes through the first preamplifier, where M and L are integers;
storing M+L output codes corresponding to M+L input codes, the first preamplifier toggles at Mth input code;
inactivating the first preamplifier and activating the second preamplifier;
modifying the input code to M−L+1;
storing output codes corresponding to each input code from (M−L+1)th input code processed through the second preamplifier;
estimating a discontinuity parameter from the output codes generated through the first preamplifier from Mth input code to Lth input code and the output codes generated through the second preamplifier from Lth input code to the Mth input code; and
adding the discontinuity parameter to output codes generated through the second and successive preamplifiers, when the discontinuity parameter is greater than a first threshold.
