摘要:
A two stage fully differential amplifier has been designed which works, in tandem with a TX-FIR, as a linear equalizer at low frequencies, not covered by the TX-FIR, and also acts as a linear amplifier at higher frequencies which are equalized by the TX-FIR. The amplifier as a frequency response which does not attenuate signals frequencies less than one twentieth of baud rate, creates gain peaking ion the region between one twentieth and one tenth of baud rate and maintains flat peak gain up to half of baud rate. Different aspects of the frequency response curve (such as dc gain, max gain and zero frequency) are completely programmable. Also, the differential amplifier has been designed from low power and process, voltage and temperature insensitive frequency response.
