Using junction FETs, a configurable configuration is achieved for very low frequencies. FETs can be of almost any type and the frequency depends on the capacitors.
Found in National Semiconductor publication from the 1980s. This gain-100 circuit can be...
We found this configuration in a 1975 publication. It can be implemented easily, as it uses only...
The high number of transistors on this radio for the medium wave range is an indication of its...
