Analog Baseband LSI can change type of filter.(NEC and NEC Electronics Successfully Develop Reconfigurable Analog Baseband LSI for Software Defined Radio)

Measuring 0.57 mm[sup.2], reconfigurable LSI for Software Defined Radio is capable of filtering unnecessary signals in frequency range of 400 KHz to 30 MHz. It can simultaneously support multiple wireless standards for existing and future mobile systems such as mobile phone, broadcasting, and wireless LAN systems. With change in pulse width of control signal, device enables several filter types, including Butterworth, Chebyshev, and Elliptic.
