1 CLIPPED SINEWAVE TO cmos . CONVERSION CIRCUIT . R2 R1. R=510K R=510K . C2. C= F. C1. TCXO. C=470pF. U1 CMOS_OUT. cmos INVERTER. CLIPPED . SINEWAVE . The above CIRCUIT converts a CLIPPED SINEWAVE waveform to a cmos waveform. The cmos . inverter selection must be rated for the frequency of operation. This CIRCUIT can work up to 100. MHz with proper selection of the inverter. This CIRCUIT presents a constant load to the TCXO since it is isolated from the output of the cmos inverter. The feedback network consisting of R1, R2 and C2 can be replaced with a single 1 Meg ohm resistor, however, the TCXO will be pulled by the output transitions of the cmos inverter. Ramon M.
