This paper presents review on Pseudo-Differential amplifier technique and Bulk-Driven MOS transistor technique for ultra-low voltage and power. By using this technique, a different design of operational transconductance amplifier (OTA) is briefly explained along with their outputs and their application. By using a pseudo-differential technique a voltage drop across the tail current is avoid as the tail-current is removed in Pseudo-differential amplifier where as by using the Bulk-Driven MOS transistor a minimum supply voltage is achieved because of the possibility in reduction of threshold vol

This work presents a single-stage, inverter-based, pseudo-differential amplifier that can work with ultra-low supply voltages. A novel common-mode stabilization loop allows proper differential operations, without impacting over the output differential performance. Electrical simulations show the effectiveness of this amplifier for supply voltages in the range of 0.3–0.5 V. In particular, a dc voltage gain of 25.16 dB, a gain-bandwidth product of 131.9 kHz with a capacitive load of 10 pF, and a static current consumption of only 557 nA are estimated at VDD = 0.5 V.

The article describes technique for modelling of ultrasonic vibrations amplifiers, which are implemented in the form of non-uniform ring-shaped waveguides, based on application of harmonic balance method. Bending vibrations of the waveguide are described by means of non-uniform integral and differential equations equivalent to Euler–Bernoulli equations in order to simplify calculation of amplitude-frequency characteristics of vibrations, particularly, to exclude the need of working with singular matrices. Using harmonic balance method, equations of vibrations are reduced to overdetermined non-

Abstract. It is a challenge to calibrate differential reflectivity ZDR to within 0.1–0.2 dB uncertainty for dual-polarization weather radars that operate 24∕7 throughout the year. During operations, a temperature sensitivity of ZDR larger than 0.2 dB over a temperature range of 10 ∘C has been noted. In order to understand the source of the observed ZDR temperature sensitivity, over 2000 dedicated solar box scans, two-dimensional scans of 5∘ azimuth by 8∘ elevation that encompass the solar disk, were made in 2018 from which horizontal (H) and vertical (V) pseudo antenna patterns are calculated.

Keynes (The General Theory of Employment, Interest and Money, Harcourt Brace and Co., New York, 1936) had rightfully argued that picking stocks is akin to a beauty contest. The chances of winning are amplified if one's choice matches the likelihood of the panel's choice. In this era of financialization, where profit-making has shifted to speculative sways rather than fundamental trade and commodity production measures (Krippner, Socio-Econ Rev 3(2): 173-208, 2005), similar beauty contests have become even more acute.

Abstract INTRODUCTION. In response to neoadjuvant therapy, pathological complete response (pCR; lack of residual disease in breast and lymph nodes), has been proposed as a prognostic marker for long-term clinical outcomes, such as disease-free (DFS) and overall survival (OS), in human epidermal growth factor receptor 2 (HER2)-positive and triple-negative breast cancer. In clinical practice, recognizing those patients likely to achieve such responses proves challenging to the oncologist, making the identification of new useful biomarkers vital. Here, we searched for potential biomarkers that an

Distributed amplifiers (DAs) are one of the most important and common wideband amplifiers that can use various arrangements in their gain cell structure. One of the gain cells that can be effective in increasing the bandwidth of a distributed amplifier is the pseudo-differential amplifier (PDA). Although pseudo-differential distributed amplifiers (PDDAs) have a wide bandwidth and amplify DC, they have a small voltage gain. In this paper, various circuits with the same power and chip area are proposed to improve the performance of PDDAs. For evaluating and comparing the performance of the propo

This work presents a single-stage, inverter-based, pseudo-differential amplifier that can work with ultra-low supply voltages. A novel common-mode stabilization loop allows proper differential operations, without impacting over the output differential performance. Electrical simulations show the effectiveness of this amplifier for supply voltages in the range of 0.3–0.5 V. In particular, a dc voltage gain of 25.16 dB, a gain-bandwidth product of 131.9 kHz with a capacitive load of 10 pF, and a static current consumption of only 557 nA are estimated at VDD = 0.5 V.

AbstractThis article realizes a low noise‐variable gain amplifier (LN‐VGA) operating at the frequency range of 31–36 GHz. The LN‐VGA consists of two amplifier stages and a gain control stage. To achieve low noise and high gain, the two amplifier stages were implemented using a single‐ended inductive source‐degeneration cascaded with pseudo‐differential neutralization capacitors. Moreover, a symmetrical splitting cascode unit topology is proposed in the gain control stage to improve the precision of phase variation and gain step within the 3‐dB bandwidth. The LN‐VGA was fabricated using a 65‐nm

AbstractThis paper studies how nonlinear distortion is generated in the combination of an inverter-based low-noise amplifier and a passive mixer. The dominant nonlinearity appears to be the quadratic $$V_{gs}V_{ds}$$ V gs V ds mixing term in the passive mixer that first causes low-frequency IM2 and then upconverts it to IM3. Adding a common-mode feedback (CMFB) cancels the IM2 in a pseudo-differential structure, and hence also reduces the IM3 caused by the cascaded second order nonlinearities significantly. The effect of CMFB gain, bandwidth and linearity were analyzed, and it is concluded tha
