Exploring non-linear operational amplifiers, this overview highlights their use in electronic circuits for signal processing tasks. Unlike linear op amps, non-linear ones exhibit complex input-output relationships, essential for applications like oscillators, comparators, and wave shaping. Their design often incorporates elements like diodes to achieve desired non-linearities, crucial in fields like communications and audio technology.
