Abstract:
In certain applications, differential amplifiers with infinite common mode rejection ratios are desirable. However, resistance mismatches due to imperfections in the manufacturing create finite common mode rejection ratio in differential amplifiers degrading their performance. Disclosed are apparatus and method for improving the common mode rejection ratio of practical differential amplifiers.
