Abstract (en)
[origin: WO2014036542A1] The core concept of this ADC is the high-speed fully-differential comparators which are clocked at 2.64 GHz and used in a 60 GHz transceiver. The comparator consists of a pre-amplifier stage, a capture stage, a regeneration cell and an output latch. The pre-amplifier stage is not clocked; therefore, the pre-amplifier stage does not suffer initialization and transient behavior effects when the clock signal switches state. The transient response of being enabled and disabled is eliminated. Instead, a capture stage transfers the contents of the pre-amplifier stage into a memory regeneration stage. The capture stage is clocked by pulses that are timed to minimize the clock kick-back generated by the memory regeneration stage. The clock kick-back is reduced even when many comparators are coupled to the PGA. The comparators are also aligned right next to each other to minimize the mismatching layout effect.
