It maintains a constant bandwidth and gain up to the specified maximum capacitance value without being affected by capacitance, frequency correction, or special connections.
In many cases where high-frequency products are used, issues such as unwanted vibrations, imperfections in ground shielding, nonlinearity, gain peaking, and bandwidth reduction due to insufficient amplifier design can arise. However, Femto's current amplifiers are designed to adequately address these problems. They prevent gain peaking, vibrations, and significant bandwidth reduction, unaffected by the signal's source parameters or wiring, with a capacitance of up to 2nF. When the capacitance is a few pF, the bandwidth of high-frequency current amplifiers significantly decreases; however, Femto's high-speed current amplifiers are not subject to this limitation and are unaffected by capacitance with a wide range. They come with two trim pots for precise offset and bias control, allowing for flexible use. Input offset current correction can be adjusted over a wide range, fully maintaining dynamics even from signals with large DC components. The bias output voltage can be adjusted within -12 to +12V using this bias trim pot.
