A 6Gb/s 6pJ/b 5mm-Distance Non-Contact Interface for Modular Smartphones Using Two-Fold Transmission-Line Coupler and EMC-Qualified Pulse Transceiver
Atsutake Kosuge, Shu Ishizuka, Junichiro Kadomoto, Tadahiro Kuroda
Modular smart phones have been attracting attention (Fig. 10.1.1) because users can freely customize their phones by purchasing modules and assembling them
ISSCC 2013 Session 14 Digital Circuits
3D Clock Distribution Using Vertically/HorizontallyCoupled Resonators
Yasuhiro Take, Noriyuki Miura, Hiroki Ishikuro, Tadahiro Kuroda
Clock distribution with low skew, low jitter, and low power for high-performance microprocessors is a significant design challenge. Although traditional H-tree clock distribution circuits are widely used, the clock skew
ISSCC 2013 Session 12 Memory
A 6nW Inductive-Coupling Wake-Up Transceiver for Reducing Standby Power of Non-Contact Memory Card by 500×
Noriyuki Miura, Mitsuko Saito, Masao Taguchi, Tadahiro Kuroda
Memory cards are widely used in electronic systems to expand internal storage area or are used as detachable media to carry data. Although cloud computing has recently drawn attention, data transfer consumes significant
ISSCC 2013 Session 11 Memory
Retrodirective Transponder Array with Universal On-Sheet Reference for Wireless Mobile Sensor Networks Without Battery or Oscillator
Haruki Fukuda, Takahide Terada, Tadahiro Kuroda
A rotating shaft in a wheel, a motor and a turbine uses sensors to measure torque, vibration, and acceleration for better control and maintenance of a machine. Such data is currently acquired in a laboratory and utilized
ISSCC 2012 Session 26 Wireless
A 2Gb/s 150mW UWB Direct-Conversion Coherent Transceiver with IQ-Switching Carrier Recovery Scheme
Takayuki Abe, Yuixiang Yuan, Hiroki Ishikuro, Tadahiro Kuroda
Short-distance (<10cm) wireless communications applications are rapidly expanding. For instance, a fast file transfer by “touch-and-proceed data communication” provides a user-friendly interface for electronic products [
ISSCC 2012 Session 16 Power Management
Voltage-Boosting Wireless Power Delivery System with Fast Load Tracker by ΔΣ-Modulated Sub-Harmonic Resonant Switching
Ryota Shinoda, Kazutoshi Tomita, Yuya Hasegawa, Hiroki Ishikuro
Recently, many applications have emerged that use wireless power delivery technology. A new standard “Qi” [1] has been established for battery operated portable devices. The rechargeable battery acts as a power buffer an
ISSCC 2010 Session 24 Memory
A 2Gb/s 1.8pJ/b/chip Inductive-Coupling ThroughChip Bus for 128-Die NAND-Flash Memory Stacking
Mitsuko Saito, Noriyuki Miura, Tadahiro Kuroda
NAND Flash memory chips and 1 controller chip are stacked in a single package for SSD applications (Fig. 24.5.1). The controller chip accesses a random memory chip by relayed transmission using inductive-coupling transce
