cold source noise measurement of a Differential Input single ended output low noise amplifier connected to a low frequency radio astronomy antenna
IEEE Transactions on Antennas and Propagation, 2018Co-Authors: Adrian Sutinjo, Budi JuswardyAbstract:We present two methods for measuring the noise temperature of a Differential Input single-ended output low-noise amplifier (DISO LNA) connected to an antenna. The first method is the direct measurement of the DISO LNA and antenna in an anechoic chamber at ambient temperature. The second is a simple and low-cost noise parameter extraction of the DISO device using a coaxial long cable. The reconstruction of the DISO noise parameter from the noise wave measurements of the DISO LNA with one terminated Input port is discussed in detail. We successfully applied these methods to the Murchison widefield array LNA and antenna.

analysis and design of ultra wideband low noise amplifier with Input output bandwidth optimization and single ended Differential Input reconfigurability
IEEE Transactions on Industrial Electronics, 2014Co-Authors: Boyu Hu, Xiaopeng YuAbstract:A CMOS low-noise amplifier (LNA) for ultrawideband universal radio is presented. Based on capacitive cross-coupled dual-gm-enhancement topology, the circuit topology could be reconfigured as different versions for single-ended or Differential Inputs. One possible Input/output resonant scheme is analyzed and may help the LNA to exhibit Input matching, low noise, and flat gain in an ultra-wide frequency band with relatively low power consumption. Both a Differential-Input-Differential-output and a single-ended-Input-Differential-output version are fabricated in 0.18 μm CMOS technology. The Differential-Input version achieves an 11-14 dB S21, ≤ -9 dBS11 within 1.4-11.4 GHz, and a minimum noise figure of 3.9 dB; the single-ended-Input version achieves a 5-8 dB S21, ≤ -10 dBS11 among 2.4-11.7 GHz, and a minimum noise figure of 6.3 dB.

a precision high voltage current sensing circuit
IEEE Transactions on Circuits and Systems I-regular Papers, 2008Co-Authors: T Dake, E OzalevliAbstract:This paper presents a precision current sensor featuring a high voltage, high gain (~ 140 dB), and low Input offset ( < 1 mV) current sense amplifier. This amplifier does not require offset trimming even for low offset applications. It is a single stage amplifier that has a common gate pMOS Differential Input pair, which makes it inherently stable. This amplifier topology allows for a wide Input common-mode range, thus increasing the versatility of current sensing circuit.
