Abstract
Pairs of second-order filters with feedback and cross coupling may be used to implement pairs of complex poles. The cross coupling may be frequency-dependent cross coupling or frequency-independent cross coupling. Frequency independent cross coupling may include coupling an internal node of a biquad filter. The pairs of second-order filters can be used together to form a complex filter. The complex filter can be used to readily provide higher order poles. The resulting complex filter can achieve higher order poles while offering reduced circuit complexity.
