摘要： A negative capacitances circuit includes first and second branches connected between a first reference voltage and a second reference voltage. The first branch includes, in series, a first biasing resistor, a first diode, a first bipolar transistor, and a first current source. The second branch includes, in series, a second biasing resistor, a second diode, a second bipolar transistor, and a second current source. The first transistor has a base coupled to a collector of the second transistor and to one input, and the second transistor has a base coupled to a collector of the first transistor and to another input. A capacitor is connected between the emitter of said first transistor and the emitter of said second transistor. A linearization resistor is coupled in parallel between the two emitters of said first and said second transistors.

摘要： A band pass filtering circuit based on a quadripole includes a serial branch having a first acoustic resonator presenting a frequency of resonance and a frequency of anti-resonance and mounted in serial with a first capacitor; a parallel branch having a second acoustic resonator resulting from the same manufacturing process as the first resonator and mounted in parallel with a second capacitor of identical value to that the first capacitor.
