This circuit is from Motorola's 1990 Linear Databook. The transistors allow equivalents and the output power depends on the supply voltage. The power supply must be 30 V symmetrical.
This circuit is from an old manual of operational amplifiers. The setting can be adapted to work...
This six-decade logarithmic current amplifier was found in a 2005 Linear Technology manual. The...
This circuit generates noise pulses for audio equipment probes. The circuit is from a 90’s 303...
