Verbruggen proposed a dynamic inverter-based amplifier as shown in Fig. 13. In the amplification (ϕ 2), an output current difference is integrated in the output capacitor. After a certain time, the switch turns off and it freezes the output voltage.
Dynamic amplifiers based on CMOS inverters attract again and have become essential to maximize energy efficiency in all analog building blocks. This chapter discusses the design of energy-efficient inverter-based amplifiers that include operating principle and biasing techniques.
This chapter discusses the design of energy-efficient inverter-based amplifiers that include operating principle and biasing techniques. It also covers recent advances to prevent performance degradation of inverter-based circuits and design examples of the state-of-the-art inverter-based amplifiers.
If this condition is violated, the VTC will become hysteretic as shown in Figure 114, and the inverter cannot be used as an amplifier. The amplifier based on the CMOS inverter has the following advantages: the gain of this amplifier is relatively large as both the NMOS and PMOS transistors add to the current change at the output node.
