In such cases, an operational amplifier (opamp) is required to sufficiently buffer the signals before they can drive the chip pad and probe parasitics. A single-stage opamp offers an attractive choice since it is power efficient and eliminates the need for frequency compensation. However, it has to satisfy demanding specifications on its stability, input common mode range, output swing, settling time, closed-loop gain and offset voltage. In this work, the settling time performance of a conventional folded-cascode (FC) opamp is substantially improved. Settling time of an opamp consists of two major components, namely the slewing period and the linear settling period. In order to reduce the settling time significantly without incurring excessive area and power penalty, a prudent circuit implementation that minimizes both these constituents is essential. In this work, three different slew rate enhancement (SRE) circuits have been evaluated through extensive simulations. The SRE candidate providing robust slew rate improvement was combined with a current recycling folded cascode structure, resulting in lower slewing and linear settling time periods. Exhaustive simulations on a FC cascode amplifier with complementary inputs illustrate the effectiveness of these techniques in settling time reduction over all envisaged operating conditions.

42	ADDRESSING CORPORATE KNOWLEDGE LOSS IN A UNIVERSITY UTILITY PLANT Kelly A McFall (9622742) 16 December 2020 (has links) <p>This research was a pilot study in a larger project that focused on how to retrieve knowledge from retiring long-term employees of a small university utility plant, incorporate that material into their existing training program, and during the process reduce the training time for current and future employees. Wade utility plant faced the retirement of eight employees with nearly 200 years of corporate knowledge within three years, but their current training program required seven to nine years to complete. The study utilized interviews, first-hand observation and partnership with current employees to explore how best to obtain the corporate knowledge that would be lost when the proletarian workers retired. The study revealed that the training program needed to be updated, and communication, trust and training evaluation continuity needed to be addressed. Due to these issues, trust was built through transparency by the researcher, and suggestions were made to management for moving forward. This study adds to the body of knowledge by utilizing knowledge capture techniques in a utility plant, highlighting effective knowledge capture techniques for proletarian workers, the importance of corporate planning for the effect of group retirements, and how incorporating proletarian workers into training creation can make a positive impact on company relationships.</p> Technology not elsewhere classified utility plants Knowledge capture Knowledge retention Baby Boomers trust cues Knowledge loss Retirement blue collar Interview Corporate Culture Communication observation techniques Training CCHP Knowledge transfer proletarian knowledge management training time reduction corporate communication building trust corporate planning implicit explicit tacit scaffolded learning OJT stationary engineer knowledge collection methodology single subject research content analysis active listening
