چکیده
Before venturing further on the design of our operational amplifier, the first line of business is to determine the optimal topology for the given specifications. The factor that clearly stands out is the high dynamic range requirement of 85 db. Several topologies are given for this task, among these telescopic op-amp is selected. Compensation techniques are used with two stage topology of telescopic operational amplifier (opamp). Miller compensation technique is used with null resistor to obtain such a high gain. The op-amp is designed on 0.13um technology CMOS process with 5 v power supply and achieved a dc gain of 85dB with a 177.1MHz unity gain frequency.

In this work a low power, low voltage and high gain operational amplifier is proposed. For this purpose a negative resistance structure is used in parallel with output to improve the achievable gain. Because of using self cascode transistors in the output, the proposed structure remains approximately constant in a relatively large output voltage swing causing an invariable gain. To evaluate the...
