Abstract
A comparator circuit with dynamic biasing comprises a comparator, first dynamic biasing generator, first extra biasing device, second dynamic biasing generator, and second extra biasing device. The comparator includes a biasing circuit, input stage, active loads, and output terminal. The input stage has a first input terminal, second input terminal, first current path, and second current path. The comparator is configured to output an output signal at the output terminal according to the first input signal and second input signal. The first dynamic biasing generator is coupled between a first detection node and the first extra biasing device coupled to the biasing circuit. The second dynamic biasing generator is coupled between a second detection node and the second extra biasing device coupled to the biasing circuit. The first and second detection nodes are between the input stage and the active loads.
