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

Claim 7:
8. The amplifier circuit of claim 1, further comprising:
a first programmable noise filter coupled at the output of the first amplifier; and
a second programmable noise filter coupled at the output of the second amplifier;
wherein each of the first and second programmable noise filters comprise:
a series capacitor;
a first variable resistor coupled between a first side of the series capacitor and a ground level, and
a second variable resistor coupled between a second side of the series capacitor and the ground level;

and wherein the control logic is further adapted to control the first and second variable resistors in each of the first and second programmable noise filters to select a zero frequency above a low frequency alias at the output of the first and second amplifiers.
