Approximate computing is an emerging trend in digital design that trades off the requirement of exact computation for improved speed and power performance. This paper proposes novel approximate compressors and an algorithm to exploit them for the design of efficient approximate multipliers. By using the proposed approach, we have …
Vasopressors and inotropes are medications used to create vasoconstriction or increase cardiac contractility, respectively, in patients with shock. The hallmark of shock is decreased perfusion to vital organs, resulting in multiorgan dysfunction and eventually death. Vasopressors increase vasoconstriction, which leads to increased systemic …

In low-bandwidth, low-noise applications of wireless sensor nodes, the sensor front-end amplifier presents a power-consumption bottleneck since its current draw is noise-limited and cannot be scaled with the low data-rate, as is possible with the DSP and RF blocks. EEG monitoring is one application where designers have targeted sub-microvolt input …
This paper presents a hybrid operational amplifier (opamp) frequency compensation topology to maximize a unity-gain bandwidth (UGBW) particularly for use in continuous-time delta-sigma modulators (CT ΔΣMs).

A WORD ON THE "DIRTY EPI DRIP" For patients with severely low perfusion in which a formal drip is not immediately feasible and push-dose pressors would be insufficient (a common example being cardiac arrest), one last-ditch effort that some ED/ICU docs can employ in attempts to increase blood pressure, heart rate, & inotropy …
At $850, the Nero XA7180 home theater amplifier is one of the most cost-effective solid-state amplifiers Sound & Vision has tested in recent years. The Class AB amp boasts a …
Today, an update on Push-Dose Pressors. I coined the name Push-Dose Pressors (PDPs) way back on episode 6. The idea was not new, anesthesiologists and resus docs have been using bolus-dose vasopressors for decades. I just thought the name was dumb, these are not boluses in the way I have always thought of them (a brief iv drip).

The Sphinx integrated amplifier may be the most roguish of the lot. Tubes? 100Wpc (200W into 4 ohms)? U.S. design and manufacture? For $1495? If that's not enough, this is the …
In this letter, a broadband linear and efficient power amplifier for base-stations in long-term evolution (LTE) applications is designed, fabricated, and experimentally verified, employing Cree's CGH40010F GaN HEMT. A novel method of baseband, fundamental and harmonic impedances control is used to provide high linearity and efficiency across a …
pressor and the cooling water temperature of the intercooler was confirmed by the ASPEN simulation. Then, the previous research results showed that the relationship between the energy consumption of the cooling tower and outlet cooling water temperature. The cooling water temperature setting can be calculated from cooling
The ductless mini-split AC units are known as the most energy-efficient air conditioning type.. Energy efficiency is denoted by a SEER rating.The most energy-efficient mini-split air conditioners can have a SEER rating above 20.In short, they can produce an incredible amount of cooling power for a fraction of electricity costs (compared to other AC types).

Until very recently, I was telling my customers that the best they could do for energy efficiency with a window AC was a 15 EER. This fits the bill for many of the products on my list, including the Midea U-Shaped Smart Inverter and LG LW1022IVSM.. Enter the GE AHTR10AC, which blows every "most energy efficient" window AC out of the …

This paper describes a new three-stage Doherty power amplifier (DPA) with an adaptive driving amplifier inserted at the input of the carrier cell. This driving amplifier controls the input power of the carrier cell to eliminate the gate leakage current at high input power levels. Using an envelope tracking technique, the gate bias voltage of the driving …
