Abstract:
1. A single-to-differential conversion circuit, comprising: a first transistor, having a third terminal to receive an input signal, a second terminal, and a first terminal; a second transistor, having a first terminal, a second terminal and a third terminal; and a transforming unit, comprising: a first induction element, having a first inductive terminal coupled to said second terminal of said first transistor, and a second inductive terminal to be coupled to a voltage source; a second induction element, having a first inductive terminal to be coupled to the voltage source, and a second inductive terminal coupled to said second terminal of said second transistor; and a third induction element, having a first inductive terminal coupled to said first terminal of said first transistor and said first terminal of said second transistor, and a second inductive terminal to be coupled to ground; wherein said first induction element and said third induction element undergo a first electrical coupling according to a first coupling parameter, and said second induction element and said third induction element undergo a second electrical coupling according to a second coupling parameter.
