This book describes the concept and design of the capacitively-coupled chopper technique, which can be used in precision analog amplifiers. Readers will learn to design power-efficient amplifiers employing this technique, which can be powered by regular low supply voltage such as 2V and possibly having a +/-100V input common-mode voltage input. The authors provide both basic design concepts and detailed design examples, which cover the area of both operational and instrumentation amplifiers for multiple applications, particularly in power management and biomedical circuit designs.
The cell interior is another world that we are only beginning to explore. Although there are a number of approaches for examining the inner workings of the cell, the reductionist approach of building up complexity appeals to many with physical science and engineering backgrounds. This volume of Methods in Cell Biology spans a range of spatial scales from single protein molecules to vesicle and cell sized structures capable of complex behaviors. Contributions include; methods for combining different motors and cytoskeletal components in defined ways to produce more complex behaviors; methods to combine cytoskeletal assemblies with fabricated devices such as chambers or pillar arrays; reconstituting membrane fission and fusion; reconstituting important biological processes that normally take place on membrane surfaces; and methods for encapsulating protein machines within vesicles or droplets.
