Dual Slope Converter

An integrating ADC is a type of analog-to-digital converter that converts an unknown input voltage into a digital representation through the use of an integrator. In its basic implementation, the dual-slope converter, the unknown input voltage is applied to the input of the integrator and allowed to ramp for a fixed time period (the run-up period).

Flash ADC

Hi Everybody: Which ADC is the fastest ADC? Flash ADC or Pipeline ADC? In my knowledge, the speed of ADC depends on its Conversion Rate or Sample Rate. This means if two type of ADC have same Conversion Rate or Sample Rate, then they have same speed, I mean they spend same time to finish one time A/D conversion.

Successive Approximation Converter

A successive approximation ADC is a type of analog-to-digital converter that converts a continuous analog waveform into a discrete digital representation via a binary search through all possible quantization levels before finally converging upon a digital output for each conversion.
