A Complementary Positive Feedback-Assisted Current Mirror-Based Level Shifter for Energy-Efficient Level Conversion for Wide Voltage Ranges

A Complementary Positive Feedback-Assisted Current Mirror-Based Level Shifter for Energy-Efficient Level Conversion for Wide Voltage Ranges 150 150
Author(s): Shin Han, Gicheol Shin, Jongmin Lee, Yoonmyung Lee

Abstract:

A complementary positive feedback-assisted current mirror-based level shifter (CPFLS) is proposed to reliably convert subthreshold signals to higher voltages. By adopting a positive feedback structure, the CPFLS mitigates the delay degradation and short-circuit current issues inherent in a prior art, WCMLS, due to its negative feedback design. Additionally, the CPFLS …

A Capacitive Stacking Mixer-First Receiver With Higher Order Capacitive Feedback

A Capacitive Stacking Mixer-First Receiver With Higher Order Capacitive Feedback 150 150
Author(s): Stef van Zanten, Ronan A. R. van der Zee, Bram Nauta

Abstract:

This article presents a capacitive stacking mixer-first receiver (MF-RX) with a higher order capacitive feedback (CFB) loop designed to increase interferer rejection right at the mixer baseband (BB) node, benefiting both the out-of-band (OOB) linearity of the passive mixer switches and the active BB circuitry. The CFB loop consists of …
