Patent ID: 7471941

Claim:
An amplifier assembly, comprising: a first stage amplifier configured to amplify an input signal, to thereby produce at an output of the first stage amplifier an amplified first signal having multiple frequency channels; a plurality of second stage amplifiers having their respective inputs coupled to an output of the first stage amplifier, each second stage amplifier being configured to amplify the amplified first signal, to thereby produce at its respective output a respective second amplified signal including the multiple frequency channels; an integrated circuit (IC) substrate, wherein the first stage amplifier and the plurality of second stage amplifiers are constructed on the IC substrate; and a process sense circuit constructed on the IC substrate for producing a sensed signal indicative of a process-based parameter of the IC substrate, wherein the process-based parameter is one or more of: a transconductance of the IC substrate; a resistivity per unit area of the IC substrate; and a threshold voltage for transistors constructed on the IC substrate.
