Quantum and Nanocomputing

This lecture covers the fundamentals of quantum and nanocomputing, discussing topics such as feedback amplifiers, analog-to-digital converters, digital-to-analog converters, sampling, quantization, noise limitations, jitter, signal-to-noise ratio, effective number of bits, and ADC architectures. The instructor explains the differences between analog and digital computing, the challenges of quantization, and the impact of noise on signal processing. Various ADC architectures are explored, including flash ADC, successive-approximation ADC, pipelined ADC, and sigma-delta ADC. The lecture concludes with a discussion on the benefits of using 1-bit ADCs in certain applications.
