Inverting_amplifier_for_gains_greater_than_10

Published:2009/7/23 21:04:00 Author:Jessie | From:SeekIC

This circuit shows an AH0014 connected as an inverting wideband amplifier, where gain must be greater than 10. If the gain is over 100, Cc can generally be omitted. For best results, use an Rf of 1 kΩ or less (to minimize the effects of stray capacitance). When Cc is in the 10-pF range, a stable gain of 20 dB is possible at 10 MHz. If peaking occurs, tower Cc to the 1- to 5-pF range. Atypical value for CF (when used) is 1 to 5 pF. A typical value for Rd (when used) is 33Ω.Figure 3-48B shows external connections for the AH0014.
