Abstract
A synthesized non-Foster time-variant filter is disclosed for matching impedance. The synthesized non-Foster time-variant filter may include a negative-inductor circuit and a negative-capacitor circuit. The negative-inductor circuit and the negative-capacitor circuit may be configured to be dynamically controlled based on a known transmit signal. The negative-inductor circuit may be configured to synthesize a negative inductance of a range of inductances. The negative-capacitor circuit may include a plurality of capacitors coupled together in parallel. Each capacitor may include a first capacitor end and a second capacitor end. The negative-capacitor circuit may be configured to synthesize a negative capacitance of a range of capacitances. The negative-capacitor circuit may include a plurality of inductors coupled together in series. Each inductor may include a first inductor end and a second inductor end.
