Circuits sometimes need a gain-of-one buffer to lower output impedance and prevent the load from interfering with the previous stage. For an application involving a 1.5-MHz, low-power transmitter and antenna, a BUF634...

The idea of using a super-regenerative radio to receive commercial FM stations can be found at various locations on the Internet. Because the circuit is so small, it might be impressive to lab visitors, especially to...

A direct-conversion radio receiver required an audio gain of 450 from a pentode vacuum tube. A pentode has a high transconductance – that is, the ratio of the change in plate current to the change of the control...

You can use three discrete transistors to build an operational amplifier with an open-loop gain greater than 1 million (Figure 1). You bias the output at approximately one-half the supply voltage using the combined...
