摘要：Self-interference cancellers are provided. The self-interference cancellers can include multiple second-order, N-path Gm-C filters. Each filter can be configured to cancel self- interference on a channel of a desired bandwidth. Each filter can be independently controlled using a variable transmitter resistance, a variable receiver resistance, a variable baseband capacitance, a variable transconductance, and a variable time shift between local oscillators that control switches in the filter. By controlling these variables, magnitude, phase, slope of magnitude, and slope of phase of the cancellers frequency responses can be controlled for self- interference cancellation. A calibration process is also provided for configuring the canceller.
