Abstract:   (3583 Views)
A power efficient gain adjustment technique is described to realize programmable gain current mirror. The dissipation power changes over the wide gain range of structure are almost negligible. This property is in fact very interesting from power management perspective, especially in analog designs. The simple structure and constant frequency bandwidth are other ever-interesting merits of proposed structure. The programming gain range of structure is from zero up to 18dB under operating frequency range from 72 kHz to 173 MHz. The maximum power dissipation of designed circuit is only 3.1 µW which is drawn from 0.7 V supply voltage. Simulation results in 0.18 µm CMOS TSMC standard technology demonstrate the high performance of the proposed structure.
