| titleOfInvention | High-speed low-imbalance dynamic comparator for high-speed analog-digital converter |
| abstract | The invention provides a high-speed low-imbalance dynamic comparator for a high-speed analog-digital converter. The high-speed low-imbalance dynamic comparator comprises a pre-amplifier, a dynamic amplifier and a dynamic latch. The pre-amplifier comprises a static amplifier, a first input imbalance storage capacitor and a second input imbalance storage capacitor. The first input imbalance storage capacitor and the second input imbalance storage capacitor are connected to a positive phase input end of the static amplifier and the negative phase input end of the static amplifier in series respectively so as to store the offset voltage of the static amplifier in the imbalance and elimination stage; the dynamic amplifier is used for amplifying the output signals of the pre-amplifier; the dynamic latch is used for amplifying the output signals of the dynamic amplifier and converting the amplified signals into a digital logic level. According to the high-speed low-imbalance dynamic comparator, the imbalance elimination technology is adopted for the pre-amplifier, the bandwidth of the pre-amplifier is optimized through an active resistor, the imbalance voltage can be reduced effectively while the high speed is guaranteed, and the dynamic amplifier which is low in power dissipation is adopted, so that power dissipation can be reduced. |
