Abstract:
A stage by stage delay current-summing slew rate controller includes a delay controller, a delay cell array, a current source array, a switch array, a load. The delay cell array includes N delay cells, the switch array includes N switches, and the switch includes N current sources, wherein N>1. The delay controller is connected with the control ports of the delay cells respectively, and the delay cells are connected with the control terminal of the switches respectively. One of the connecting terminals of the switch is connected with the output end of the current source, and the other end of the connecting terminals of the switch is connected with one end of the load, and the other end of the load is connected to the ground.
