[12] The figure below shows a current amplifier utilising an op amp. 2 Is Rs 1₁ I₁ OUT R₂ ww 1.1-3 will be marked from your image file named Q1. The consequence of failure to comply with the instructions here is a marks penalty. Images must preferably be jpg, but heic, png and bmp are also good, and even a pdf will be accepted. Multiple files may be uploaded using the base name and appending 1, 2, etc. Please use the template below on lined or unlined paper for your answer, scan or photograph your physical work along with your physical student card, signature, and date (on each page), and upload the file to the AMS. If you wish, your photograph need not be visible. (2) 1.1. Using ideal opamp analysis, analyse for the current gain of the amplifier circuit alone (excluding the source RS and the load RL). Show that it is given approximately by: To Io R₂ Ai = 1 + Is 1₁ R₁ 1.2. Analyse for the input resistance Rin of the current amplifier circuit alone. Ignore the loading of the source Rs, and the load RL. (2) 1.3. Analyse for the output resistance Rout of the current amplifier circuit alone. Ignore the loading of the source Rs, and the load RL.
