AbstractA frequency compensation technique for three‐stage amplifiers is introduced. The proposed solution exploits only one Miller capacitor and a resistor in the compensation network. The straightness of the technique is used to design, using a standard CMOS 0.35‐µm process, a 1.5‐V OTA driving a 150‐pF load capacitor. The dc consumption is about 14µA at DC and a 1.8‐MHz gain–bandwidth product is obtained, providing significant improvement in both (MHzpF)/mA and ((V/µs)pF)/mA performance parameters.
