Because membrane proteins are critically important in biological processes and among the most prevalent drug targets, a thorough understanding of their structure and function is highly desired. However, this has been difficult to achieve due to the laborious nature of existing tools and techniques for membrane protein studies. This paper presents a new microsystem concept for high throughput membrane...
In this study, we demonstrate the feasibility of three dimensional (3-D) photoacoustic imaging using a monolithic CMOS MEMS capacitive ultrasonic sensor. The sensing membranes are released by a post-CMOS metal etch and sealed by silicon dioxide. Nine membranes, each with an inner diameter of 60 µm, form a single detection unit with a capacitance value of 292.5 fF. The measured sensitivity is 151 mV...
This paper proposes a cost-effective RF power cell manufactured in an advanced 0.13 um CMOS technology. Without adding additional masks, cost, and process, the power performance can be improved just by using the standard N-well and shallow-trench-isolation processes to form a higher resistive region. This ldquoPseudo-Drainrdquo structure increases the breakdown voltage to more than 4.3V and is higher...
