发明名称 Second order active high-pass filter with cross-coupled feedback for Q enhancement
摘要 An apparatus comprising an input circuit, a cross coupled active circuit and an output circuit. The input circuit may be configured to generate a first portion of an intermediate signal in response to an input signal. The cross coupled active circuit may be configured to generate a second portion of the intermediate signal in response to a feedback of an output signal. The output circuit may be configured to generate the output signal in response to the intermediate signal. The output signal may pass frequencies above a target frequency.
