Abstract
An integrated circuit includes a first high-pass filter having an input coupled to receive a first signal and an output coupled to a first input of a first differential pair of transistors. A second high-pass filter includes an input coupled to receive a second signal and an output coupled to a second input of the first differential pair of transistors. The second signal may be a complementary signal of the first signal. A second differential pair of transistors includes control electrodes coupled to a first voltage supply terminal. A boost circuit is coupled between the second differential pair of transistors and the first voltage supply terminal. A low-pass filter is coupled between the first differential pair of transistors and the second differential pair of transistors.
