Claim 0:
1. An electrical integrated circuit, comprising:
a frequency comparator configured to determine operational characteristics of an electrical circuit connected to an optical modulator; and
an electrical driver configured to drive a phase shift of a first optical signal carried on a first arm of the optical modulator relative to a second optical signal carried on a second arm of the optical modulator, the electrical driver comprises:
an inverting buffer having a fixed gain inverter, an adjustable gain inverter, and a non-inverting amplifier, and
wherein an amplification strength of the adjustable gain inverter is adjustable and set based on the operational characteristics, and wherein a driving voltage that is applied to the adjustable gain inverter, the fixed gain inverter, and the non-inverting amplifier is adjustable and set based on the operational characteristics, and wherein the non-inverting amplifier is arranged to boost an input signal to the fixed gain inverter and the adjustable gain inverter.
