  • Publication number: 20090102582
    Abstract: At microwave frequencies, the use of transmission lines as a design element becomes interesting due to the small wavelengths. Inductors as part of an on-chip resonator can be made with a shorted stub, which is a transmission line, shorted at the end. Placing a MIM-capacitor at the beginning of the shorted stub can make a resonator. Shielding this kind of resonator by means of vias or stacked vias enables very compact filter designs.

The amplifier according to the invention further includes a third and a fourth transistor T3 and T4 which form a differential pair; degenerated by means of a degenerating impedance Req which has a nominal value equal to that of the load impedance RL of the amplifier, which differential pair (T3, T4) is intended to be controlled by means of a control signal (?Vin/2, Vin/2), in anti-phase with the input signal (Vin, ?Vin). The invention permits to double the output current Iout of the amplifier without, however, increasing its power consumption.
