Classification: H03K

Abstract:
A delay cell, comprising:a first input receiver on a first branch for receiving a first input to control a first current on the first branch, the first branch having a first output node capacitively coupled to a power supply node;a second input receiver on a second branch for receiving a second input to control a second current on the second branch, the second branch having a second output node capacitively coupled to said power supply node;a first current source coupled between the first output node and said power supply node;a second current source coupled between the second output node and said power supply node; anda first current diverter coupled to the first branch for diverting current on the first branch away from the first input receiver and a second current diverter coupled to the second branch for diverting current on the second branch away from the second input receiver,wherein each of the first and second current diverters is a diode.
