1. **Common Mode Feedback Circuit with Backgate Control**: This patent introduces a common mode feedback (CMFB) loop designed for differential amplifiers. It accurately senses the output common mode of a differential circuit and provides feedback to the gates of tail current transistors. What sets this circuit apart is its ability to adjust the output common mode voltage, a feature that many existing CMFB loops lack. By incorporating a control circuit to manage backgates, the circuit enables adjustable output common mode voltage, even in varying process, voltage, and temperature conditions.

2. **Active Cascode Circuit Using Backgate Control**: This patent presents an active cascode circuit featuring a control circuit that regulates the gate to source voltage (VGS) of at least one transistor within the circuit. This innovative design allows for the adjustment of the input voltage (Vin) without modifying device geometry or altering drain current. As a result, this advancement enhances the control and optimization of available headroom for input voltage in low voltage designs, leading to increased bandwidth and output impedance for given power levels.
