A low-voltage CMOS negative impedance converter for analogue filtering applications

W. JENDERNALIK
A novel current-inversion type negative impedance converter (CNIC) is presented. It is built without the use of any resistors. Furthermore, a second-order low-pass filter based on this CNIC is also analysed. It shows a bandwidth of 50 MHz at 320 µW power consumption and 2 V supply voltage when realized in a 0.35 µm CMOS process.
  
Key words: 

CMOS, negative impedance converter, continuous-time filters
