Özet

In this study, a low-voltage current mirror to use in differential pairs as an active load is introduced. The proposed current mirror which can operate at +/- 0.5 V has high output impedance and low input impedance. The proposed structure employs the principle of voltage level-shifting for PMOS transistors. The voltage level-shifting operation has been achieved by using the bulk voltage at this structure. Spice simulations also justify this current mirror's outstanding performance with a bandwidth of 11 GHz using an external capacitor at an input current of 200 mu A.
