... TSH310 4 Power Supply Considerations Correct power supply bypassing is very important for optimizing performance in high-frequency ranges. Bypass capacitors should be placed as close as possible to the IC pins to improve high-frequency bypassing. A capacitor greater than necessary to minimize the distortion. For better quality bypassing, a capacitor of 10nF can be added using the same implementation conditions. Bypass capacitors must be incorporated for both the negative and the positive supply ...

... TSH310 6 Intermodulation Distortion Product The non-ideal output of the amplifier can be described by the following series: due to non-linearity in the input-output amplitude transfer, where the input is V component the fundamental and one-frequency (one-tone) input signal contributes to harmonic distortion. A two-tone input signal contributes to harmonic distortion and to the intermodulation product ...

... TSH310 8 Active Filtering Figure 31: Low-pass active filtering, Sallen-Key IN IN From the resistors R and R fb amplification configuration: We assume the following expression as the response of the system: The cut-off frequency is not gain-dependent and so becomes: The damping factor is calculated by the following expression: The higher the gain, the more sensitive the damping factor is. When the gain is higher than preferable to use some very stable resistor and capacitor values ...
