The conversion time for a 10-bit successive approximation A/D converter, for a clock frequency of 1 MHz is

Concept:For n-bit conversion, the conversion time for successive APPROXIMATION A/D CONVERTER is given as:Conversion Time = n x Tclk\(T_{clk}=\frac{1}{f_{clk}}\)The conversion time (tcon) will be:\(t_{cov}= n\times\frac{1}{f_{clk}}\)Calculation:Given: n = 10, and fclk = 1 MHz\(t_{con}= 10\times\frac{1}{1 \ MHz }\)Conversion time = 10 μsFor n-bit conversion, the conversion time for different ADC are:Counter type ADC: (2n – 1) TclkSuccessive approx. time ADC: n TclkFlash type ADC: TclkDual slope ADC: (2n+1 – 1) TclkCounter type ADC and successive APPROXIMATE ADC uses DAC.Counter type ADC uses linear search and successive approximation type ADC uses binary search.A ring counter is USED in successive approximation type ADC.Flash type ADC is the fastest ADC.Flash type ADC requires no counter.For an n-bit ADC, flash type ADC requires (2n – 1) comparators.Dual slope ADC is the most ACCURATE.
