A 0.19-PEF Bandwidth/Power Scalable Dynamic Amplifier 150 150
Author(s): Yihang Cheng, Yihan Zhang, Huaqiang Wu, Sining Pan

Abstract:

This letter presents an energy-efficient dynamic amplifier. It utilizes source-coupled input boosting and time-domain differential sampling techniques to boost the effective input signal by $4\times $ compared to its floating inverter amplifier (FIA) prototype without noise or power penalties. With discharge-based dynamic biasing, the bandwidth (BW) and power of the amplifier …

A 14-b Energy-Efficient BW/Power Scalable CTDSM With a Frequency-Controlled Current Source

A 14-b Energy-Efficient BW/Power Scalable CTDSM With a Frequency-Controlled Current Source 150 150
Author(s): Xinjie Wu, Xiaopeng Yu, Nick Nianxiong Tan, Zhong Tang

Abstract:

This work presents a 14-bit energy-efficient bandwidth (BW)/power scalable continuous-time delta–sigma modulator (CTDSM) for sensor interfaces in IoT applications. To ensure low noise for small input signals and achieve BW/power scalability, it is built around Gm-C integrators biased via a linear frequency-controlled current source (FCCS). The FCCS …
