Abstract
- A single‐stage multi‐path operational transconductance amplifier (OTA) is presented. The proposed amplifier uses the transconductance enhancing technique in an upgraded folded cascode (FC) amplifier. It significantly improves the DC gain, unity‐gain bandwidth and slew rate compared with previous FC amplifiers with the same power consumption. Simulation results in 90 nm complementary metal‐oxide semiconductor (CMOS) technology show that the proposed OTA achieves a 59.1 dB DC gain and a gain bandwidth of 650 MHz, which makes it suitable for fast‐settling switched‐capacitor circuits.
