(a) Derive an expression for the short-circuit noise current ino at the output of the bipolar current mirror depicted in Assume the input source is noiseless. (b) Repeat, but for the MOS mirror. What are the expressions for the noise fl oor and the corner frequency of i no 2 ? How are they affected if the input current is doubled?
