... capacitance and smaller leakage current.The main trade-offs in preamplifier design are to achieve reasonable gain boost, minimize thermalnoise, and limit bandwidth, while keeping reasonable settling ... charges obtained during the Integrate 1 phase are held. In the final Integrate 2phase, -Vs+, Verror, -Vs- are integrated and amplified. Since the error voltage remains constant, and sensingsignals ... thedrains of input pairs from output nodes, and keep drain nodes tracking the input, thus minimize effectiveinput capacitance. A Vgs-eff of 0.25V, and a bias current Idc of 100 A are used in...
