A linearization technique for bipolar amplifiers based on derivative superposition

A mm‐wave LNA employing current re‐use and non‐linearity cancellation in 28 nm CMOS for automotive RADAR and 6G receivers

“…Bipolar junction transistors (BJT) can alternatively serve to compensate for the negative value of $$\text{g}_{\text{m}3}$$ as reported in Ref. [11–13], although these techniques using BJTs are reported at low frequencies. As BJTs and MOSFETs are different types of devices, there can be a huge mismatch between them, resulting in significant phase misalignment at mm‐wave frequencies, leading to poor non‐linearity cancellation.…”
