Rf receiver
I'm working on a simple receiver circuit. Just to receiver a 27MHz signal to drive a motor. This is how the circuit goes..
Tuned circuit ----> Amplifier ----> halfwave rectifier ---> transistor as a switch to drive the motor
When i only tested the motor circuit itself... just using a 3V battery to run it... it doesn't... but when i use power supply of only 2.18V it runs...
anybody can explain? because of its current?
