Hi everyone,. I have designed a low noise amplifier which needs + 4.4 volts and -5 volts (~10mAs) for biasing purposes. Uptill now on bench testings i was using switching DC power supplies. However now i want to integrate it with my datasystem and wondering which way i can bias my amplifier, keeping noise from the bias lines minimum. I have put bunch of bypassing capacitors close to the circuit. Should i just get some batteries & use resistors in series or if there are clean regulated DC OEM type power supplies i can mount in a small box?
