  • Abstract
    A 260 MHz continuous-time 5th-order Gm-C biquad low-pass filter with an automatic tuning circuit is described. The Nauta¿s transconductor is applied for high frequency design. The cutoff frequency tuning can be achieved by adjusting load capacitance in two ways. The filter cutoff frequency is 260 MHz. The HD3 is less than -50 dB for input signals up to 400 mVpp. The power consumption is 24 mW with 1.8-V supply voltage.
