My customer focused on HMC856. The HMC856 is a time delay element.
He unusually works under negative bias.
The customer knows the device of both power supplies, but is puzzled over the device only for negative power supplies.
What kind of connection will be recommended if a customer has access to a device and the DC of a common power supply?
Is the method to strengthen a power supply line, and to functionalize as GND of HMC856 possible?
Are there any documents on this subject?
