Abstract
The differential signals at the outputs of a differential amplifier quickly change in response to common mode changes in the output differential signals. The amplified input signals amplified by the differential amplifier quickly change in response to common mode changes in the differential signals input into the differential amplifier. A bias voltage input to the differential amplifier is isolated to remove low-frequency components from the bias voltage.
