Mixed mode analog to digital converter and method of operating the same |
摘要 |
An analog to digital converter in accordance with the inventive concept may include a reference voltage generation circuit outputting first and second reference voltages; a decompression part decompressing amplitude of an analog input signal and the first and second reference voltages; a flash ADC converting the decompressed analog input signal into a first digital signal with reference to the decompressed first and second reference voltages; and a successive approximation ADC converting the analog input signal into a second digital signal according to a successive approximation operation with reference to the first digital signal and the first and second reference voltages. |

1. An analog to digital converter (ADC) comprising:
a reference voltage generation circuit outputting first and second reference voltages; a decompression part decompressing an amplitude of each of an analog input signal, the first reference voltage, and the second reference voltage by a decompression magnitude; a flash ADC converting the decompressed analog input signal into a first digital signal with reference to the decompressed first and second reference voltages; and a successive approximation ADC converting the analog input signal into a second digital signal according to a successive approximation operation with reference to the first digital signal and the first and second reference voltages.
