Abstract:
An amplifier including at least a first amplifier stage, the at least first amplifier stage comprising:a first plurality of auxiliary amplifiers, each of said auxiliary amplifiers in said first plurality having an input and an output and including a prescribed offset voltage level; anda first plurality of output transistors, each of said output transistors in said first plurality being in a prescribed circuit relationship with the output of a respective one of said first plurality of auxiliary amplifiers forming a first plurality of auxiliary amplifier-output transistor pairs that are connected in parallel circuit relationship with each other, wherein each of said output transistors in said first plurality of output transistors is in an OFF state until an input signal supplied to the inputs of said first plurality of auxiliary amplifiers has a signal magnitude equal to or greater than the offset voltage level of the respective auxiliary amplifier in circuit relationship to said respective output transistor, whereby linearity in the frequency domain of said amplifier is improved.
