半速率预加重电路
摘要：
本发明揭示了一种半速率预加重电路，包括i+1个电流源I0、I1、...、Ii，i+1个选择电路第一选择电路、第二选择电路、...、第i+1选择电路和负载电路，所述第一选择电路、第二选择电路、...、第i+1选择电路分别将所述电流源I0、I1、...、Ii选择性地连接至第一输出端或第二输出端；i为大于或等于2的自然数；其中，所述第一选择电路、第二选择电路、...、第i+1选择电路通过所述电流源I0、I1、...、Ii选择性地组合至所述第一输出端和第二输出端而预加重传输信号。本发明提出的半速率预加重电路，实现了传输信号的预加重和去加重。
摘要（英）：

The invention discloses a half-rate pre-emphasis circuit including i+1 current sources I0, I1,... and Ii, i+1 selection circuits including a first selection circuit, a second selection circuit,... and an (I + 1)th selection circuit and a load circuit. The current sources I0, I1,... and Ii are selectively connected to a first output end or a second output end by the first selection circuit, the second selection circuit,... and the (I + 1)th selection circuit and i is a natural number larger than or equal to 2, wherein the first selection circuit, the second selection circuit,... and the (I + 1) th selection circuit pre-emphasizing transmission signals through selective combination of the current sources I0, I1,... and Ii with the first output end and the second output end. The half-rate pre-emphasis circuit realizes pre-emphasis and de-emphasis of the transmission signals.
