Driving circuit of light-emitting element and method of generating driving signal therefor
Abstract:
A driving circuit includes a first delay circuit, a rise-detection circuit, a fall-detection circuit, a first filter, a second filter, and an adder. The first delay circuit delays an input signal. The rise-detection circuit detects a rise of the input signal. The fall-detection circuit detects a fall of the input signal. The first filter gives a first gain-frequency response to an output signal of the rise-detection circuit. The second filter gives a second gain-frequency response to an output signal of the fall-detection circuit. The adder adds an output signal of the first filter and an output signal of the second filter to an output signal of the first delay circuit.
