Continuous shrinking of dimensions in VLSI technologies along with the growing trend of portable devices led to the necessity of power reduction from the past decade. With the advent of portable and implantable gadgets especially in biomedical field, low power analog circuit design is gaining utmost importance now-a-days. The study of various circuit level low power techniques like Bulk Driven (BD), Source Degeneration (SD), and class AB configuration is carried out. The advantages and the disadvantages of each of these techniques have been discussed along with the tabulation of the technology used and the power dissipation in each technique.
