Hi there I'm a student intern, very new to ADE XL, with basic knowledge of Analog IC in Common Source Amplifier Characteristics.
I am seeking some help in some guide in using the Corner Analysis / Optimization tools in ADE XL.
Firstly, I need to optimize a Common Source Amplifier circuit as shown, with one single bias point, Vindc, maintain > gain of 15 dB @ saturation region [2]
I'm allowed to manipulate the W/L / R_D / Vindc. While keeping the V_DD constant @ 1.2V.
The circuit must work in -40, 27, 70 and 125'C at the corners 'tt', 'ss', 'ff', 'fnsp' and 'snfp'.
The problem arise caused by my corner and temperature settings, the Vout vs Vin generated is offset, and I couldn't determine the best Vindc point.
I've been struggling to manipulate to W/L and R_D / Vindc such that to minimumize this offset to all my circuit to provide a good consistent gain of > 15 dB ?
I've been struggling for 4 days with this question given by my supervisor...
