Low-power JFET dual operational amplifiers. Internal frequency compensation. Pulse techniques must be used that will maintain the junction temperature as close to the ambient temperature.
Frequency Compensation Techniques for Low- Power Operational Amplifiers - Rudy G H Eschauzier, Johan Huijsing. Frequency Compensation Techniques for Low- Power Operational Amplifiers is intended for professional designers of integrated amplifiers, emphasizing low- voltage and low- power solutions. It does so by explaining existing techniques and introducing several new techniques including Hybrid Nested Miller compensation, Multipath Miller Zero cancellation and Multipath Conditionally Stable compensation. All compensation techniques are treated in a stage- number- based order, progressing from a single transistor to circuits with six stages and more. Apart from discussing the mathematical basis of the compensation methods, the book provides the reader with the factual information that is required for practicing the design of integrated feedback amplifiers and many worked out examples.

What is more, many bipolar and CMOS operational amplifier realizations, along with their measurement results, prove the effectiveness of the compensation techniques in real- life circuits. Many of the presented bipolar circuits operate at supply voltages down to 1. V, while several CMOS amplifiers that function correctly just slightly above this voltage are demonstrated. The lowest measured power consumption amounts to 1. W for a class AB CMOS op. Amp with 1. 20d. B gain. Despite this attention to low voltage and low power, the frequency compensation strategies provided are universally applicable.
