Abstract

The invention provides a pulse generating circuit, a device using the same and an information transmitting method. The pulse generating circuit can easily generates a high frequency band pulse with a low energy consumption by using a simple circuit without using a high-cost semiconductor process. The pulse generating circuit is composed of: inverter circuits (101-109) which are connected in series according to a predetermined amount of stage; a plurality of NAAD circuits (110-113) which are connected with the input / output side of one of the inverter circuits (101-109) every other one stage, generating a pulse with a width which is equal to a delay of each stage of the connected inverter circuits (102, 104, 106, 108); and a NOR circuit (114) which obtains an 'or' of the output of the NAND circuits (100-113).

Description

technical field

[0001] The present invention relates to a pulse generation circuit suitable for UWB (Ultra Wide Band) communication, an electronic device using the circuit, and an information transmission method using the circuit. Background technique

[0002] UWB communication is a communication method for high-speed and large-capacity data communication using a very wide frequency band. The communication methods using broadband signals include the traditional spread spectrum-based method and the Orthogonal Frequency Division Multiplexing (OFDM) method. However, UWB is an ultra-wideband communication method using very short pulses, also known as pulse radio (IR) ) way of communication. In the IR method, regardless of conventional modulation, modulation and demodulation can be performed simply by manipulating the time axis, and it is considered that simplification of circuits and reduction in power consumption can be expected (see Patent Documents 1, 2, and 3).
