近来，短距离板对板互连被广泛地用于便携式系统和可穿戴设备中，以将许多组件容纳到极其紧凑的占用空间中。特别是，便携式设备，如智能手机和平板电脑需要超过1Gb/s的数据传输通过AP板和高分辨率宽屏显示板之间的~ 1 mm的距离。大多数显示器接口是用有线F-PCB连接器实现的，但是，它们遭受：1）高制造成本，2）连接器和标准插座的大形状因子，以及3）连接器和插座的大电容值使通道特性劣化。到目前为止，已经尝试了各种通信接口来实现低成本、小形状因子和低能量操作，但是成功有限。由于其低能量操作，双相脉冲调制用于板对板通信而不是基带传输[1-5]。该方法对数据“1”使用正脉冲电流，对数据“0”使用负脉冲电流，并且接收器通过在精确的时间对数据进行采样来恢复数据，这需要精确的延迟控制单元。然而，双相脉冲调制消耗显著的功率，因为：1）在每个数据处采样的电流脉冲消耗TX中的大电流，以及2）需要高功率延迟控制单元来精确地控制采样时间。
Recently, short distance board-to-board interconnections are widely employed in portable systems and wearable devices to accommodate many components into an extremely tight footprint. In particular, portable devices such as smart phone and tablet require over 1Gb/s data transfer through ~1mm distance between AP board and a high resolution wide screen display board. Most of display interfaces are implemented with wire-line F-PCB connector, but, they suffer from: 1) high manufacturing cost, 2) the large form factor of the connector and standard socket and 3) large capacitance values of the connector and socket degrading the channel characteristics. So far, various communication interfaces have been tried to realize low cost, small form factor and low energy operation, but with limited success. The bi-phase pule modulation was used in board-to-board communication rather than base-band transmission due to its low energy operation [1-5]. This method used the positive pulse current for data `1' and the negative pulse current for data `0', and the receiver recovered the data by sampling the data at the exact time, which requires an accurate delay control unit. However, the bi-phase pulse modulation consumes significant power because: 1) current pulses sampled at every data consume large current in TX, and 2) a power hungry delay control unit is required to exactly control the sampling time.
