Abstract: An analog-to-digital converting device includes N-stage first analog-to-digital converters (ADCs), a second ADC, a first calibration circuit, a data recovery circuit and an output circuit. The N-stage first ADCs has a first sampling frequency that is (N+1)/N times of a second sampling frequency, and converts an input signal into first quantized outputs. The second ADC has the second sampling frequency, and converts the input signal into a second quantized output. The first calibration circuit calibrates offsets of the first quantized outputs and the second quantized output to generate third quantized outputs and a fourth quantized output. The data recovery circuit outputs, by the second sampling frequency, one of the third quantized outputs as a fifth quantized output, and subtracts the fifth quantized output from the fourth quantized output to generate output data. The output circuit generates an output signal according to the third quantized outputs and the output data.

Abstract: A semiconductor die package includes a high dielectric constant (high-k) dielectric layer over a device region of a first semiconductor die that is bonded with a second semiconductor die in a wafer on wafer (WoW) configuration. A through silicon via (TSV) structure may be formed through the device region. The high-k dielectric layer has an intrinsic negative charge polarity that provides a coupling voltage to modify the electric potential in the device region. In particular, the electron carriers in high-k dielectric layer attracts hole charge carriers in device region, which suppresses trap-assist tunnels that result from surface defects formed during etching of the recess for the TSV structure. Accordingly, the high-k dielectric layer described herein reduces the likelihood of (and/or the magnitude of) current leakage in semiconductor devices that are included in the device region of the first semiconductor die.
