The proposed OTA is then used for the analog implementation of the CI speech processing sections: a variable gain amplifier (VGA) for the AGC, a Tow-Thomas bandpass biquad for the BPF bank, and an envelope detector for feature extraction.

Indeed, electronic transconductance tuning expressed in (2) can be extrapolated to electronically tuning the parameters of the speech processing sections, as further illustrated with three examples, namely a variable gain amplifier (VGA), a Tow-Thomas bandpass biquad and an envelope detector.

An Electronically Tunable Transconductance Amplifier for Use in Auditory Prostheses

An envelope detector (square-law-type detection) on the user terminal is used to down-convert the mm-wave signals and eliminate the frequency instability and poor phase-noise characteristics of the two independent signals.

After passing through the antennas, at the designated user terminal nn the received downlink and P2P signals are down-converted to their associated IFs by the envelope detector. This can help eliminate the frequency instability and poor phase-noise characteristics of the two independent optical signals.

It is then transformed into a DC signal by an envelope detector. This DC signal is so small that it cannot be directly applied to the power amplifier.
