该论文提出一种嵌套电流镜单级放大器，以超低功耗(3.6μW)和极小面积(0.0013mm²)驱动0.15-15nF的宽范围容性负载，解决了多级放大器因频率补偿导致的功率和面积效率瓶颈问题。
Italy 1 2 For active-matrix LCDs [1] that have thousands of buffer amplifiers integrated in its column-driver ICs, ultra-low power and area circuit solutions are continuously urged to meet the market pressure on cost, image quality and display size. Multi-stage amplifiers have dominated those buffers due to their reliable DC gain, output swing, gain-bandwidth product (GBW) and slew rate (SR). Yet, different kinds of frequency compensation are also useful for stability, bottlenecking the capacitive-load (CL) drivability, power and area efficiencies. Classical single-stage amplifiers were underused in those buffers due to their limited capability in most metrics despite being almost unconditionally stable at any CL and tiny in size. In view of this, it is beneficial to revisit the fundamental
