A high-speed continuous-time bandpass VHF filter in MOS technology

A very high frequency (VHF) second order bandpass filter has been developed. The filter is based on a minimal transistor-only all-MOS high-frequency generalized impedance converter (GIC) that simulates a passive RLC ladder. The filter poles are obtained using the internal lumped capacitances of the MOS transistor. Using this structure a very high frequency filter is obtained consuming a small chip area. The center frequency is controlled by an external bias current to the circuit. Using the GIC, a bandpass filter can be implemented in MOS technology with center frequencies in excess of 50 MHz. The filter is simulated for center frequencies of 47 MHz, 54 MHz and 63 MHz.<<ETX>>
