ELECTRONIC DESIGN
Introduction: basic on analog and digital design.
Input stages and signal amplifier: project examples: offset and bias current nulling in integrator amplifiers; current feedback amplifiers (CFA); antialiasing filter for A/D conversion and CD audio filter; switch capacitor filters; digital fiters with design elements.
Noise: noise properties, dinamics and sources. Op amp noise and S/N ratio. Photodiode amplifier application. Low noise integrated circuits.
Analog-digital conversion: ADC definition; oversamping and noise shaping; ΣΔ modulator, ΣΔ converters architecture; conditioning system for sensors; examples of OpAmp conditioning system; ADC practical application: ADC selection and temperature measurement, electronic scale and power measurement.
Output stages and power amplifiers: large signal amplifiers. A, B, AB and C classification. Armonic distortion and power devices. Safe operating Area (SOA) protections. Efficiency. Integrated power amplifiers and devices.
Design project examples in several microelectronic field (biomedical, radiofrequency and power).
