“…Current-based sensors [6,10] or dedicated measurement modules [11,12] have also been employed to measure or predict the performance of some blocks in the receiver chain. All these strategies require connections of the BIT circuitry either to the signal path or to the bias network, and sometimes require the insertion of switches to reconfigure the system under test and to route the RF signal to internal meters in test mode.…”

This paper presents two approaches to characterize RF circuits with built-in differential temperature measurements, namely the homodyne and heterodyne methods. Both non-invasive methods are analyzed theoretically and discussed with regard to the respective trade-offs associated with practical off-chip methodologies as well as on-chip measurement scenarios. Strategies are defined to extract the center frequency and 1 dB compression point of a narrow-band LNA operating around 1 GHz. The proposed techniques are experimentally demonstrated using a compact and efficient on-chip temperature sensor for built-in test purposes that has a power consumption of 15 μW and a layout area of 0.005 mm 2 in a 0.25 μm CMOS technology. Validating results from off-chip interferometer-based temperature measurements and conventional electrical characterization results are compared with the on-chip measurements, showing the capability of the techniques to estimate the center frequency and 1 dB compression point of the LNA with errors of approximately 6% and 0.5 dB, respectively.

“…The built-in CMOS current sensor (BICS) was designed to monitor the current consumption (I DD ) of integrated circuits, as it is a simple method for detecting defects missed by conventional logic tests [Cimino 2007]. The sensor uses a parasitic 10 Ω resistor in the IC interconnecting layer; the effect of the process parameter variation is reduced by a ratiometric circuit.…”

The paper makes a brief overview of traditional methods of measuremet of electric current and shows in more detail relatively new types of current sensors. These include Hall sensors with field concentrators, AMR current sensors, magnetooptical and superconducting current sensors. The influence of the magnetic core properties on the error of the current transformer shows why nanocrystalline materials are so advantageous for this application. Built-in CMOS current sensor are important tools for monitoring of the health of integrated circuits. Of special industrial value are current clamps which can be installed without breaking the measured conductor. Parameters of current sensors are also discussed, including geometrical selectivity. This parameter specific for current sensors means the ability to suppress the influence of currents external to the sensor (including the position of return conductor) and also suppress the influence on the position of the measured conductor with respect to the current.

“…Conventionally, changes in circuit parameters and working environments were included in the design, which affects the overall performance of the circuit. For instance, inserting dummy sensors in addition to active and passive devices reduces the effect of such parametric variations . Since the mismatch of input impedance and output impedance of the LNA leads to minimize power transformation, with the proper tuning of a tank circuit, LNA can be optimized .…”

Summary This paper presents a Novel automated Multi Objective Ant Lion Optimization Algorithm (MOALO) aided Radio Frequency Low Noise Amplifier (RFLNA) design for wireless applications. This MO‐ALO algorithm has been used to resolve numerous nonlinear engineering problems with exceptional results. In regard of this, the MOALO algorithm is used to optimize the performance parameters of RF LNA. The RF LNA topology has a cascode structure with inductive source degeneration topology using 0.18 μm CMOS technology for wireless applications. This optimization using the MOALO algorithm is implemented using the Xilinx tool, which optimizes the active and passive parameters of RF LNA, and the optimized RF LNA is simulated using the Agilent ADS and Cadence OrCAD Capture 17.2 tools; the results are compared with the existing works. This optimized RF LNA provides high Gain, Low Noise Figure, and better Stability with less power and low circuit complexity.
