Differential amplifier circuit for use in a read channel for a magnetic recording system |
摘要 |
Briefly, in accordance with one embodiment of the invention, a circuit includes: at least one differential amplifier. The differential amplifier is coupled in a circuit configuration so that the differential output voltage signal of the differential amplifier circuit includes a scalable second-order harmonic component of the differential input voltage signal applied to the differential amplifier circuit. Briefly, in accordance with another embodiment of the invention, a method of applying a differential input voltage signal to a differential amplifier circuit to produce a differential output voltage signal includes the step of: driving the differential amplifier circuit so that the differential output voltage signal of the differential amplifier circuit includes a second-order harmonic component of the differential input voltage signal.
