To accommodate links of varying lengths, the AFE includes an analog peaking equalizer followed by a post-amplifier. The input preamplifier is important for achieving the required input sensitivity. A DC bias current is introduced through the feedback resistor in a conventional shunt-shunt feedback nMOS transimpedance amplifier (TIA) to level-shift the output, obviating a following level-shifting stage. The fabricated AFE occupies 0.89 mm2 in a 90-nm CMOS process and dissipates 138 mW from a 1.3-V supply.

The CPU also has a 256-KByte secondary unified cache on top of the 64-KByte primary split cache. Compared to the previous SH-MobileR processor, SH-MobileR2 introduces four peripheral modules: a DDR-SDRAM controller, an Interconnect Buffers with 128-Kbyte embedded Media RAM, an improved Video Processing unit (VPU5F), and an enhanced 2-D Graphics accelerator for higher performance in map rendering and graphic applications. Low-power consumption is achieved by optimizing blends of a 90 nm CMOS triple Vth cells, and applying four power-down modes.

This converter requires only four flying capacitors for realizing all the conversion ratios, and when achieving 4times and 5times, the original redundant flying capacitor is reconfigured to the dual-branch architecture to enhance efficiency. The advantages of both level-shifter and PN-switches control schemes are combined as a hybrid gate control scheme in eliminating reversion current. Gate switching loss of power transistors is reduced by a charge recycling mechanism. The design was fabricated in a 0.35 mum 50 V CMOS process. Measurement results confirm that the converter could achieve an output voltage higher than 14 V for a supply voltage that ranges from 2 V to 5 V.

To meet the stringent requirements of Noise Figure (NF) and IIP3, a capacitor cross-coupled (CCC) common-gate LNA and a novel high-linearity, low-flicker noise Gilbert Mixer are adopted. The LNA achieves 26 dB variable gain by using digital controlled current-steering technique and a resistive attenuator. To overcome the gain roll-off at the high frequency channels, a current reuse self-biased post-LNA buffer is proposed as the interface between the VGLNA and Mixer. In addition, a fully integrated DC Offset Correction (DCOC) circuit with switchable high-pass corner frequency, is introduced to realize both low high-pass cutoff frequency and short settling time. A wideband integer-N synthesizer using an adaptive frequency calibration (AFC) of dichotomizing technique, settles less than 200 mus for LO generation.
