Abstract: A bias circuit includes a first transistor and a second transistor configured as a first current mirror. A first current source is arranged between a supply node and the first transistor first terminal. A bias circuit output is coupled to the second transistor second terminal. A second current mirror is coupled to the first current mirror and the bias circuit output. A second current source is arranged between the supply node and the second current mirror. A third transistor in a diode-connected configuration is coupled between the first transistor second terminal and a ground. Alternatively or in addition, the bias circuit includes a first variable capacitor coupled between the second transistor first terminal and the second transistor second terminal. A fourth transistor has a control terminal coupled to the supply node, a first terminal coupled to the supply node and a second terminal coupled to the second transistor first terminal.

Abstract: There is provided a phase shifting device and method of manufacturing the same. The device comprises an auto-transformer comprising a primary winding configured to receive an input signal; and two secondary windings, wherein a first one of the two secondary windings is in phase with the primary winding and a second one of the two secondary windings is out of phase with the primary winding. The device also comprises a first switch coupled to an output signal of the first one of the two secondary windings of the auto-transformer; and a second switch coupled to an output signal of the second one of the two secondary windings of the auto-transformer. Output signals of the first and second switches are couplable to an output of the phase shifting device.
