Abstract
A circuit comprising a current source, a first amplifier, and a second amplifier. The circuit may be used to provide for crossing point compensation of a CMOS driver as a function of a supply voltage. The current source may be configured to present a reference current. The first amplifier may be configured to (i) receive the reference current as a load, (ii) receive a first voltage, and (iii) present a second voltage responsive to the first voltage. The second amplifier may be configured to (i) receive the second voltage and (ii) change a current at a node responsive to the second voltage.
