- This paper presents the design and implementation of a variable bandwidth amplifier intended for ultra-low-power biomedical implants in 65nm CMOS, providing tunable gain-bandwidth in three modes: 0.9 MHz, 1.7 MHz, and 2.3 MHz with consistent 56 dB DC gain. The amplifier consumes 180nW static power in the lowest bandwidth mode, and consumes 315 nW static power in the full bandwidth mode with an 8 pF load from a 0.9-V supply voltage. To illustrate the concept, the presented programmable bandwidth amplifier is applied in a dual-mode ΔΣ modulator aiming for sensing/measuring stage of a cardiac pacemaker.
