... RHF310 3 Power supply considerations Correct power supply bypassing is very important for optimizing the performance of the device in high-frequency ranges. The bypass capacitors should be placed as close as possible to the IC pins to improve high-frequency bypassing. A capacitor greater than 1 µF is necessary to minimize the distortion. For better quality bypassing, a capacitor can be added, which should also be placed as close as possible to the IC pins ...

... RHF310 6 Bias of an inverting amplifier A resistance is necessary to achieve good input biasing, such as resistance R shown in Figure 26. The value of this resistance is calculated from the negative and positive input bias current. The aim is to compensate for the offset bias current, which can affect the input offset voltage and the output DC component ...
