Hello,
I have an elementary electronics question. I have attached a circuit i need help solving. V1=5V and V2= -30V. what i need is to be able to control the switch with 3.3V logic. Vcntrl(0V)=off ---Vout=-30V; Vcntrl(3.3V)=on ---Vout= -27V. I dont care what type of device is used as the switch...
I dont believe that thermal noise is the dominate issue. The pcb is sitting on a bare hard surface in a room that averages about 20C. There is also very little heat produced during operation due to the fact that the entire circuit only draws a max of 200uA. I plan to do spectral analysis of...
A coworker suggested that i change my bypass and bulk capacitors. He claims that he has seen cases were using ceramics with too low of esr can increase 1/f noise. Have either of you ever heard of that happening?
Thanks biff and dave. I have notice the effects of thermal noise on the board. All feedback resistors in the design are 1M. If i change them to 10k the noise in the low region improves by a couple dB, but it also increases the power draw to an unacceptable level.

Hello,
I am relatively new to PCB layout. I was wondering if anyone on here has any considerations or do's and donts to reduce 1/f noise in an analog circuit. I cant change the ICs being used due to power and customer restraints, so the noise generated by them is what it is. I was wondering if...
