13ns High-Speed Comparator with no Hysteresis

The TS_CMP_13ns_X8 is a high-speed comparator with no hysteresis and a propagation delay of 13ns while having a differential input signal of 25mV. The comparator consumes current of 350μA. The circuit features an Enable signal turning on/off the comparator. The proposed circuit is a free-running comparator, therefore, no clock signal is needed, as depicted in the comparator symbol in Figure 1. The comparator requires a bias current of 20uA supplied from an external biasing circuit and can provide an output toggling between 0V and Vcc. A comparator hysteresis can be added via feedback circuit.
