A floating resistor on a current source technique is introduced. All the transistors are saturated leading to higher frequency response than previously proposed techniques. Simulated results, using HSPICE level 3, for a 214 k floating resistor have shown a-3dB frequency of the order of 1 GHz. Its total harmonic distortion at 10.7 MHz and including 2% worst case transistor mismatches is less than 62 dB for fully differential applied signals up to 2 V peak to peak. 1991, The Institution of Electrical Engineers.
