Original Abstract
This paper proposes an operational transconductance amplifier-capacitor-based (OTA-C) negative group delay (NGD) circuit for transimpedance-mode systems. The application areas extend from audio to sensor signal anticipation. Post-layout simulated NGD value of about 200 mu s to 100 ns is observed to be achievable with three different capacitor values without any resistive passive components. The operation range varies from 700 Hz to 700 kHz. The NGD and the operation range are shown to be flexible without gain dependency. An example design is built for a specific NGD value of 15 mu s and time-domain analysis is done with both a single-tone sinusoidal and a band-limited audio record in the range of 1 Hz-7 kHz. The calculated Root Mean Square Error for audio input to the system is only 4.70%.
