摘要
The effects of noise on random jitter in multistage broad-band amplifiers are analyzed. Limiting amplifiers are compared to automatic gain control (AGC) amplifiers with different gain profiles. Results are presented for a 10-Gb/s AGC amplifier implemented in an SiGe process with f(T) of 45 GHz. Active peaking techniques were used to achieve a maximum gain of 48 dB with 7.8 GHz of bandwidth. The amplifier demonstrates low jitter and less than 0.5 dB of peak-to-peak output amplitude variation over a 50-dB input amplitude range. It consumes 30 mW of power from a 3.3-V supply. The amplifier core occupies 0.1 mm(2) and requires no external components.
