I want to create a simple transmitter using AD633, the problem is need to connect the input to a microphone or mp3 player.
what pre amp circuit should i use, will LM386 with gain of 200 from the datasheet work?
I'm currently using a function generator as a carrier input signal.
Hello, can anyone help me build Automatic Cut off Charger or
Smart Battery Charger for 7.4 Volts - 2 x 3.7volts Lithium Polymer Battery 3500mah.
Charger will automatically turn off when its 8.2volts(safe voltage) or 8.4 volts - fully charged.
I try to search from the internet,and i found...
I want to make an OP-AMP using LM324 - QUAD OP-AMP.
Input is 50mVolts & out is 10Volts so the Gain is 200.
1st op-amp is for Buffer.
My question is, should i use all three remaining op-amps?
Or should i use only one ?
Please answer thanks :)
I just want to Design a Cascade BJT Amplifier Two Stages,
but my problem is, Im only given two values Vin = 50mVp @ 25Khz and Vo= 3Vp,
I dont really know where to start.. They say that i need to draw a transfer curve to find the Value of Ic.
Please Help me. :cry::cry::cry:
