摘要： Provided is a frequency conversion mixer. The frequency conversion mixer includes a transconductance stage, a switching stage, a load stage, a current bleeding circuit, and a bias stage. The transconductance stage receives an RF signal, and outputs a current corresponding to a voltage of the RF signal. The switching stage switches the current which is outputted from the transconductance stage in response to a local oscillation signal, for frequency conversion the RF signal into an intermediate frequency (IF) signal. The load stage is connected between the switching stage and a supply voltage terminal. The current bleeding circuit is connected parallel with the switching stage, especially, embodying inverter structure with transconductance stage to get not only current bleeding effect but also current reuse effect, and one resonant inductor for reducing noise which is generated in parasitic capacitance at node between transconductance stage and switching stage. The bias stage is connected between the transconductance stage and a ground terminal, and has the switched biasing technique for allowing not only the stable bias current but also lowering the flicker noise.

摘要： An apparatus for introducing electromagnetic perturbation into a target device includes a piezoelectric transducer configured to deflect in response to an applied voltage and a perturber configured to deflect in response to deflection of the piezoelectric transducer. The deflection of the perturber causes electromagnetic perturbation, and in some cases a phase shift, in the target device. The electromagnetic perturbation may also be used to tune microwave devices such as filters, resonators, and oscillators.
