Abstract
A comparator () includes a first input transistor (M) having a drain coupled to a gate and drain of a first diode-connected transistor (M) and a gate of a first current mirror output transistor (M), and a second input transistor (M) having a drain coupled to a gate and drain of a second diode-connected transistor (M) and a gate of a second current mirror output transistor (M). Sources of the first and second current mirror output transistors are connected to a supply voltage (V). Gates of the first and second input transistors are coupled to first (V) and second (V) input signals, respectively. Sources of the first and second diode-connected transistors are coupled to drains of the first and second current mirror output transistors, respectively. A latch circuit (M,M) is coupled to the drains of the first and second current mirror output transistors.
