For characteristic analysis of the 24 KHz audio, the 10-ms, 18-band quasi-ANSI filter bank has been proposed and designed for advanced hearing aids. To greatly reduce the computation complexity, several time-domain multirate signal processing techniq

Adaptive voltage positioning (AVP) scheme is widely adopted in the high-load voltage regulation modules (VRMs) because it helps VRMs reducing almost half the number of output capacitors for the same design without using AVP. The AVP scheme is claimed

This brief presents an implementation of ultralow-power microcontrollers that use a separate clock network voltage (SCNV) to correct unexpected errors produced by on-chip variations (OCVs). Separating the clock network voltage requires amendments in

The ANSI S1.11 1/3-octave filter bank is suitable for digital hearing aids, but its large group delay and high computational complexity complicate matters considerably. This study presents a 10-ms 18-band quasi-ANSI S1.11 1/3-octave filter bank for p

To overcome significant PVT variation in ultra-low-voltage (ULV) operation, a new in-situ error detection and recovery mechanism is proposed to optimize circuit design for typical-case. The proposed technique detects glitch of a (ctitical-path) circu
