Dual threshold voltages domino design methodology utilizes low threshold voltages for all transistors that can switch during the evaluate mode and utilizes high threshold voltages for all transistors that can switch during the pre charge modes. We employed standby switch can strongly turn off all of the high threshold voltage transistors which enhances the effectiveness of a dual threshold volt...

A 240 $\times$ 160 single-photon avalanche diode (SPAD) sensor integrated with a 3D-stacked 65nm/65nm CMOS technology is reported for direct time-of-flight (dToF) 3D imaging in mobile devices. The top tier occupied by backside illuminated SPADs 16 notation="LaTeX">$\mu {\mathrm{ m}}$ pitch and 49.7% fill-factor. SPA...

The use of adaptive equalizers at the front end of receivers is becoming a necessity as the data rates increase without channel improvements. Adaptive equalizers can be implemented using data-aided or non-data-aided schemes [1], with the latter requiring less area and power. Previous non-data-aided adaptive schemes [2-3] implement an asynchronous analog algorithm where the power spectrum of the...

Source-series-terminated (SST) drivers offer the advantage of providing a large range of termination voltages, making them particularly suitable for multi-standard I/Os [1, 2]. Many standards (e.g. [3]) however, call for larger vertical eye openings that require raising the dc supply voltage from the l.OV limit for thinoxide devices in 65nm technology to 1.2 or 1.5V. These requirements are addr...

Since their conception and success in human trials, the flexibility and spatial resolution of retinal prostheses have been of major interest. Clinical studies have revealed that hundreds of channels are needed to restore functional visual perception [1], and more sophisticated waveforms present advantages over biphasic pulses [2]. Initial designs targeted stimulation current levels up to 1mA to...

This work proposes a RX front-end structure, which is used for channel equalization of 25Gb/s high-speed links. design includes two parts, linear equalizer and decision feedback equalizer. Linear consists the variable gain amplifier, continuous-time output buffer, provide 19dB peaking around Nyquist frequency. The half-rate with one speculative tap cascaded after buffer to eliminate residual in...

Two techniques are presented in this paper for a software-defined radio (SDR) receiver robust to out-of-band interference. Voltage gain is realized at IF simultaneously with low-pass filtering to mitigate blockers and out-of-band intermodulation distortion. A 2-stage polyphase harmonic rejection (HR) mixer concept robust to gain error achieves 2-6 HR of more than 60dB for 40 samples without tri...
