Abstract
Various devices, circuits and systems including filter sections for creating complex poles are described herein. For example, various circuits including transistors, tuning capacitors and resistors are described. In the circuits, the tuning capacitor is electrically coupled between the gate and source of the transistor, and the resistor is electrically coupled to the gate of the transistor. In one configuration, the circuit input is applied to the gate of the transistor via the resistor, and the output is taken from the source of the transistor. In another configuration, the input is applied to the source of the transistor, and the output is taken from the same source. In yet another configuration, the input is applied at the source of the transistor and the output is taken from the drain of the transistor.
