  • Patent number: 12658916
    Abstract: A combined low noise amplifier (LNA), mixer, and voltage-controlled oscillator (VCO) circuit (i.e., an LMV cell) includes four dual-gate transistors. These four transistors include series-connected first and second transistors between a ground rail and a first local oscillator signal node and series-connected third and fourth transistors between the ground rail and a second local oscillator signal node. The first and third transistors are LNA components. The second and fourth transistors are cross-coupled VCO components. Front and back gates of the transistors are biased with different combinations of an RF input signal and complementary local oscillator signals generated on the first and second local oscillator nodes.

  • Publication number: 20250267927
    Abstract: A disclosed low noise amplifier (LNA) includes a common-emitter amplifier (CE-A), a common-gate amplifier (CG-A) and various passive devices in CE-A and CG-A. CE-A includes an NPN-type bipolar junction transistor (BJT) with emitter and collector (E/C) regions and a base region between the E/C regions and connected to an input node. CG-A includes P-channel field effect transistor (PFET) with source and drain (S/D) regions, a channel region between the S/D region, and a gate adjacent to the channel region. The drain region of the PFET is connected to an output node. Additionally, a common inductor, collector region of the BJT, and source region of the PFET are connected at an intermediate node. The LNA is implemented on a three-dimensional integrated circuit (3DIC) with the BJT and FET on different chips and with passive devices in back end of the line regions between the BJT and FET.
