  • Publication number: 20230095020
    Abstract: Radio Frequency (RF) circuit (amplifiers, mixer, etc.) design with RFIC, e.g., implemented in CMOS, CaAs, SiGe, or other silicon processes, suffers performance variations (gain phase, frequency, bandwidth, nonlinearity) due to wafer process variations, temperature changes, and supply voltage changes, and random variations. In this invention, methods are proposed to precisely calibrate the bias current of all active devices in the system, and to precisely calibrate the gain of individual path leading to each amplifiers such that the same Pout is achieved for all antenna elements in the system.

  • Publication number: 20220060153
    Abstract: A power amplifier (PA) linearization technique with a wider linearized power range is proposed. Proposed two types of linearizers with cross-coupled PMOS and NMOS configuration. The idea is to use a complimentary device compared with the PA core device, and the behavior of Cgs of the linearizer are also complimentary to the PA itself. In the other words, the overall Cgs of the PA with the linearizer would be constant without leading to non-linear waveform. Both linearizers can effectively compensate not only AMAM but also AMPM. First type of linearizer can be integrated with PA cores, and second type of linearizer can be used in the IMN. Both linearizers have effective IM3 reduction in different corner.

  • Patent number: 10270399
    Abstract: A gate bias circuit for a plurality of GaAs amplifier stages is a transistor coupled to a temperature compensation current received from a CMOS control stage. A plurality of pHEMPT amplifier stages are coupled to the gate bias circuit and to a control voltage which switches the amplifier stage. A selectively controlled stage pass transistor enables a current mirror between the gate bias circuit and each stage amplifying transistor. The penultimate pHEMPT amplifier stage is coupled to a CMOS amplifier. A CMOS circuit provides both the temperature compensation current by a proportional to absolute temperature (PTAT) circuit and the control voltage enabling each pHEMPT transistor to receive its input signal in combination with the gate bias voltage.
