In particular, low noise JFETs exhibit low input gate currents that are desirable when working with high impedance devices at the input or with high value feedback resistors (e.g., ≥1MΩ). Operational ...
There are two types of preamplifiers for magnetic phono cartridges. An example of the most common type is the one described in the March 2002 issue of SILICON CHIP. It has the RIAA equalisation ...
