Title: 0.7V ultra low noise supply
Post by mixed_signal on May 3^rd, 2016, 11:37am

Hi,
I want to test an LNA IC. I want to use supply of 0.7V and make it as low noise as possible. I plan to use a 6V lead acid battery and then use a voltage regulator as follows

Can anybody suggest better ways? The lab power supplies that I have make the noise figure 1dB worse.
