LOW DISTORTION DRIVER FOR ANALOG-TO-DIGITAL CONVERTER (ADC)
Abstract:
A driver includes an inverting amplifier stage and a non-inverting amplifier stage. The inverting amplifier stage includes an inverting amplifier input and an inverting amplifier output. The inverting amplifier stage includes a first voltage follower which includes a first voltage follower input coupled to the inverting amplifier input and a first voltage follower output coupled to the inverting amplifier output. The inverting amplifier stage includes a first gain-boost amplifier coupled to the first voltage follower. The non-inverting amplifier stage includes a non-inverting amplifier input and a non-inverting amplifier output. The non-inverting amplifier stage includes a second voltage follower which includes a second voltage follower input coupled to the non-inverting amplifier input and a second voltage follower output coupled to the non-inverting amplifier output. The non-inverting amplifier stage includes a second gain-boost amplifier coupled to the second voltage follower.
