Overview
This brief presentation summarizes ADCs and DACs, covering their performance metrics, common topologies, performance trends, and limiting factors.
Performance metrics
Static and dynamic performance metrics are described, including differential nonlinearity (DNL), integral nonlinearity (INL), signal-to-noise ratio (SNR), signal-to-noise-and-distortion ratio (SNDR), spurious-free dynamic range (SFDR), and harmonic distortion (HD).
Topologies
Different ADC and DAC architectures are discussed, including Flash, successive-approximation register (SAR), pipelining, and time-interleaved designs.
Performance trends and limitations
Factors affecting ADC and DAC performance are examined, such as dynamic range, speed, resolution, energy consumption, and clock jitter.
Power and performance trade-offs
Relationships between power consumption and conversion rate and resolution (as measured by SNDR) are analyzed, and energy trends across different design approaches are discussed.
