Abstract
In a class of embodiments, an adaptive equalization circuit that implements a joint adaptation algorithm. Other embodiments are receivers that include such an adaptive equalization circuit, and joint adaptation equalization methods. The equalization circuit includes a filter having a low-frequency-gain path (sometimes referred to as a low-frequency filter) and a high-frequency-boosting path (sometimes referred to as a high-frequency filter). The high-frequency filter typically includes a high-pass filter in series with an amplifier having adjustable gain. A high-frequency-boosting tuning loop controls the adjustable gain applied by the high-frequency filter. A low-frequency-gain tuning loop controls the adjustable gain applied by the low-frequency filter.
