Dan-
Not exactly sure what you are saying in the 1st paragraph. What are you getting at with: "coil would not oscillate in a drift free manner"? I _think_ Frank was suggesting using inductive loads on the output, not the input. If you use a choke as a collector load, the differential amplifier gain will be frequency dependent (dependent on the impedance of the choke at any particular frequency). -Ray WB6TPU ________________________________ From: [email protected] [mailto:[EMAIL PROTECTED] On Behalf Of Daniel Jackson Sent: Monday, March 03, 2008 11:55 AM To: [email protected] Subject: [soft_radio] Re: Usage of inductors on collectors of a GIlbert cell I think I know what you are saying, I use a coil on pin 8 of the MC1496 as a choke with a 10 MHz mixer input to the choke. If you are talking about using the idea of coil self resonance then in that case the coil would not oscillate in a drift free manner. The coil makes a good input choke though. I got a model of that in my Spice files for upload later. Dan
