Power management unit (PMU) is commonly used to manage power modules to achieve high efficient performance for integrated circuits. Inside the PMU, controllers that belong to different power modules could be pretty much similar. If the discrete featu

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

In recent years, many popular technologies require a highthroughput ultra-long FFT processor, such as the OFDM and FMCW radars. In order to get high throughput, we use the MDC architecture to design the FFT processor. In addition, we added the 2-epoc

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

Based on an error-flattened, non-uniform-region linear-approximation algorithm, this brief proposes a low-error and a cost-efficient design procedure for realizing an optimized shift-and-add Logarithmic Unit (LU), which uses minimum hardware to meet

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
