—The design issues of a single-transistor-control (STC) low-drop-out (LDO) based on flipped voltage follower is discussed in this paper, in particular the feedback stability at different conditions of output capacitors, equivalent series resistances (ESRs) and load current. Based on the analysis, an STC LDO was implemented in a standard 0.35-m CMOS… (More)
In order to be useful for mobile systems, the switching frequencies of modern buck converters (BCs) are in the MHz-or even GHz-range to enable the use of compact off-chip inductors and capacitors , or even on-chip Ls and Cs . However, such high switching frequencies increase both the switching loss and the gate-drive loss, and degrade BC light-load… (More)
Acknowledgment: The development of BSIM3v3.2 benefited from the input of many BSIM3 users, especially the Compact Model Council (CMC) member companies. TSMC for their valuable assistance in identifying the desirable modifications and testing of the new model. their guidance and support.
Microelectrodes are widely used in the physiological recording of cell field potentials. As microelectrode signals are generally in the μV range, characteristics of the cell-electrode interface are important to the recording accuracy. Although the impedance of the microelectrode-solution interface has been well studied and modeled in the past, no effective… (More)
