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.
Transmission...
sorry for late reply,
i need is computation and design. i have sample design using bjt but in simulation i've done, it doesn't look like the sample.
do all Pierce Oscillator use crystal?
and yes, its a homework.

computation for this?
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...
Actually i don't know what my Teacher really wants us to do. I don't really know if its a audio amp or what.
All i know is, this circuit is connected to a Function Generator - as Vi source of 50mV at 1khz.
1st Stage is op-amp using TL074 , gain of 200 and Vout of 10Volts.
Opamp A - He call...
Here's my computation and schematic diagram. Im using 400k for resistor feedback and 30k- R1.
We use dual power suppy. :-D
can u please check my solution?? thanks!!

What values should i set Rf or R1?
If i use 20 gain and 330k for Rf i'll get R1 = 17368.42, and for gain...
the signal comes for a Signal Generator or test with mp3 player.
This op-amp is connected to a push-pull amp, with 6.125 watts output and input of 7volts peak-coming from op amp.
Parts is not so limited, we order it in Manila or buy it online, i choose LM324 because its easy to solve and this...
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 :)
