Question

3. A PMOS transistor has the gate and drain tied together. The source voltage is V-SV, drain voltage VD-2V, threshold voltage Vrp--2v. μ.Cgox-8 μΑ/V2 and L-10μm . The transistor supports a current of Isp a) Calculate the width of the transistor W and gate oxide thickness tgox Note: μ,-480 cm 2/(V-s) and Ego, (relative permittivity of Si02-39 b) Using a scaling factor S-5, if only the length L is scaled by 1/S with all other parameters remaining the same, calculate the current Isp through the transistor ofsio) -39
