Title: region 0 in dc operation point Post by James Bond on Jul 6th, 2007, 7:59am Hi, does anybody know 'region 0' in dc operation point mean triode region or cut off region ? I am simulatiing passive mixer, I found the four transistors are all working in the region 0 state, and I still get IF output. But in my memory, region 0 represents cutoff state, and region 1 represents triode state, and one pair of switches of the mixer should work in the triode region, the other two should work in the cutoff state. Best Regards James |

Hi, Ken, Thank you for the reply, could you kindly tell me where to input this command ? I tried in CDS.log window, but it returns ''unbond variable -hs'' |
