This work reports a multipurpose highly linear ultrawideband amplifier with gain-bandwidth product (GBP) of 1.75 THz, the highest reported in any monolithic microwave integrated circuit (MMIC) process. A transimpedance is cascaded distributed amplifier, emulating receiver subsystem. Using diamond heat spreader, to dissipate from transistors, amplification subsystem can achieve very high output ...

Abstract Wearabl smart devices have become an important method to monitor people’s health. This research work aims offer a relatively optimum solution amplify the biomedical signal in case of wearable devices. is done by using single-stage amplifier and Operational Transimpedance Amplifier (OTA) stage. The OTA stage uses typical 2-stage topology, with first-stage differential pair, second commo...

A low-power, high-gain CMOS low noise amplifier (LNA) for use as the first stage of a subsampling receiver is proposed. The performance of +96-dB voltage gain and less than 1-dB Noise Figure (NF) with very low power consumption is reported for the first time and makes it suitable for subsampling mixer with Track and Hold (T/H) circuit. The LNA contains both tuned and inductorless amplifier stag...

This paper presents five-stage and seven-stage traveling-wave amplifiers (TWA) in a 0.12m SOI CMOS technology. The five-stage TWA has a 4–91-GHz bandpass frequency with a gain of 5 dB. The seven-stage TWA has a 5–86-GHz bandpass frequency with a gain of 9 dB. The seven-stage TWA has a measured 18-GHz noise figure, output 1-dB compression point, and output third-order intercept point of 5.5 dB, ...

Introduction It is critical for a firm to manage its demand when launching a new product successfully. It is well studied that demand of a new product diffuses in the market, driven by consumers’ word-of-month (Rogers 1995, Mahajan et al. 2000). However, in most previous research on dynamic pricing, the demand diffusion dynamics has largely been omitted (Elmaghraby and Keskinocak 2003). Without...

High-throughput DNA metabarcoding has gained recognition as a potentially powerful tool for biomonitoring, including early detection of aquatic invasive species (AIS). DNA based techniques are advancing, but our understanding of the limits to detection for metabarcoding complex samples is inadequate. For detecting AIS at an early stage of invasion when the species is rare, accuracy at low detec...
