  • Highly Linear Inductively Degenerated 0.13 mu m CMOS LNA using FDC Technique

    • In this paper, a highly linear, inductively degenerated, common source narrowband LNA is presented. An extremely simple feed-forward distortion circuit (FDC) which consists of an appropriately sized ac-coupled diode connected NMOS is proposed. This circuit generates distortion components at output, when added at the input node as a feed forward element (M-6). These distortion components partially cancel the 3rd order nonlinearity of the cascode pair (M-2 and M-3), thus improving the overall linearity of LNA. The prototype is manufactured in standard 0.13 mu m CMOS process from IBM. Simulation and partial measurement results show the S11 and S22 to be -19.27dB and -7.14dB respectively at 2.45GHz. The simulation results of the LNA demonstrate a power gain of 18.5dB, NF of 4.38dB, input referred 1dBCP of -11.76dBm and IIP3 of +0.7dBm consuming 27.7mA from 1.0V power supply. The proposed LNA achieves the best input referred IIP3 reported in recent literature using 0.13 mu m CMOS in 2.4GHz frequency band.

  • Design of a broadband current mode class-D power amplifier with harmonic suppression
  • 2016
  • Ingår i: Analog Integrated Circuits and Signal Processing. - : Springer. - 0925-1030 .- 1573-1979. ; 89:1, s. 15-24

    • Current mode class-D power amplifiers (CMCD-PA) are attractive for fully integrated PA implementation as the output capacitance of the active device can be absorbed in the output matching network that can be realized with minimum number of components. This paper presents a simplified design approach for CMCD PA design using an integrated balun transformers. Expressions are derived for the optimum device sizing for second harmonic suppression resulting in improved efficiency. An expression of amplifier efficiency as a function of device size is is presented proving that current mode class-D amplifier yields higher higher efficiency than a class-E amplifier for the same device size. The amplifier is implemented in 130 nm CMOS process and encapsulated in QFN package. Measurement results show that the amplifier exhibits broadband response between 1.4 and 2.1 GHz with peak output power of 26.8 dBm at 1.8 GHz using a 2.4 V supply. PAE remains above 40 % for the entire range while peak PAE is 48 %. Results show a good match between simulation and measurement work. Voltage sweep of the amplifier shows that it can be used in supply modulation based LINC techniques.
