Dr. Puchades completed his Ph.D. on thermally actuated MEMS resonators to measure the viscosity of fluids in 2011. In 2016 he completed a 2-year postdoctoral appointment providing innovating insight on the physical characteristics of doped electronic-type-separated single wall carbon nanotubes and developing novel devices. He currently teaches undergraduate courses in Electrical Engineering and has taught graduate-level Microelectronic Engineering courses in MEMS Design, Fabrication and Test.

His current research interests include collaborations to explore high frequency and sensing applications of new materials such as carbon nanotubes and other nanomaterials (graphene, 2D metal chalcogenides, phosphorenes, borophene, nanowires, 2-dimensional electron gas (2DEG) heterostructures, etc.). He is also interested in expanding research and development of MEMS devices and applications of thermal, electrostatic and piezoelectric MEMS resonators, piezoelectric energy harvesting, multi-sensor networks, and system integration.

Dr. Puchades has significant industry experience having worked as an RF device engineer and BiCMOS technology development engineer for Motorola and Freescale Semiconductor in Phoenix, Arizona from 2000 to 2005. He was responsible for CMOS and high-voltage technology integration at the 0.18-µm node. While at Freescale he organized a Device Physics Seminar for process engineers, obtained his Six-Sigma green belt accreditation and lead the resolution of several high-impact device engineering issues. He coop’d at Advanced Vision Technologies and National Semiconductor during his undergraduate studies.

3 Credits
Covers basics of DC circuit analysis starting with the definition of voltage, current, resistance, power and energy. Linearity and superposition, together with Kirchhoff's laws, are applied to analysis of circuits having series, parallel and other combinations of circuit elements. Thevenin, Norton and maximum power transfer theorems are proved and applied. Circuits with ideal op-amps are introduced. Inductance and capacitance are introduced and the transient response of RL, RC and RLC circuits to step inputs is established. Practical aspects of the properties of passive devices and batteries are discussed, as are the characteristics of battery-powered circuitry. The laboratory component incorporates use of both computer and manually controlled instrumentation including power supplies, signal generators and oscilloscopes to reinforce concepts discussed in class as well as circuit design and simulation software.
