ABSTRACT:
Systems and methods are provided for positive and negative feedback of cascode transistors for a power amplifier. The systems and methods may include a first cascode stage comprising a first common-source device and a first common-gate device; a second cascode stage comprising a second common-source device and a second common-gate device; a first degenerative element or block provided for the first common-source device; a second degenerative element or block provided for the second common-source device; a first positive feedback block or element that connects a first gate of the first common-source device with a second drain of the second common-source device; and a second positive feedback block or element that connects a second gate of the second common-source device with a first drain of the first common-source device.
