A voltage controlled oscillator includes a first NMOS transistor having a base terminal configured to receive an input signal INP and a drain terminal connected to an output node OUTN, a second NMOS transistor having a base terminal configured to receive an input signal INN and a drain terminal connected to an output node OUTP, a third NMOS transistor having a source terminal connected to a low voltage supply VSS and a drain terminal connected to source terminals of the first NMOS transistor and the second NMOS transistor. A first PMOS transistor includes a base terminal connected to the output node OUTP and a drain terminal connected to the output node OUTN. A second PMOS transistor includes a base terminal connected to the output node OUTN and a drain terminal connected to the output node OUTP.
